b. 69.97 m/s
c. 7.14 s
Further explanationGiven
height = 250 m
vox = 25 m/s
Required
distance from base
vertical speed(vy)
time to reach ground
Solution
voy = 0
h=voy.t + 1/2 gt²
h = 1/2gt²
250 = 1/2.9.8 t²
t=7.14 s
x = vox.t
x = 25 x 7.14
x = 178.5 m

What are the velocity and acceleration of the ball at the highest point in its path? What are the velocity and acceleration of the ball at the highest point in its path? V=0,a=0. V=0,a=9.8m/s2up. V=0,a=9.8m/s2down. V=9.8m/supa=0. V=9.8m/sdowna=0
Answers
Answer:
v = 0 and a = 9.8 m/s²
Explanation:
When an object reaches the highest point, its velocity is equal to 0. After reaching the highest point, it starts to decelerate. The acceleration is in the downward direction and it is equal to g i.e. 9.8 m/s².
So, the velocity and acceleration of the ball at the highest point in its path is 0 and 9.8 m/s² downward.
Hence, the correct option is (d).

Group of answer choices
heating from the crust and mantle
heating from the core and mantle
cooling from the crust and core
cooling from the core and mantle
Answers
Answer: Heating from the crust and mantle.
Explanation: Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.
The convection currents that cause this cycle to take place is driven by heating from the crust and mantle. Hence, option (a) is correct option.
What is rock cycle?A crucial idea that illustrates the changes between the three primary rock types is the "rock cycle" (metamorphic, igneous and sedimentary). Simply put, it is a series of processes that create and modify the various types of rocks found in the Earth's crust.
The solid crust of Earth serves as a heat insulator for the planet's warm interior. The molten rock in the mantle, below the crust, is known as magma. Convection currents are created by the intense heat and pressure that exists within the earth. The tectonic plates that make up the earth's crust shift as a result of these currents.

Explanation:
Answer:
a changing electric field creates a magnetic field.
Explanation:
if you have a circuit and you send AC current through (AC = Alternating current) so that the electrons move back and forth, they will create a changing electric field.
This produces a magnetic field (because that's what the universe does).

Electric Field Hockey
In this activity, you will again explore the relationship between an electric field and charged particles in the field, but this time you’ll have a gaming challenge. To begin, open Electric Field Hockey.
Directions:
On the control bar, make sure that the Puck is Positive and the Field boxes are checked. Also, make sure that the Practice option is selected.
Your aim is to score goals by manipulating the black puck (test charge) into the blue-colored bracket (goal) on the right. Think smart and place positive source charges (red) and negative source charges (blue) in such a way that the black puck moves into the goal.
Note that when you place a red, positive source charge in the hockey field, a red arrow appears on the black puck (test charge) showing the force the positive charge exerts on the puck. Similarly, when you place a blue, negative source charge in the hockey field, a blue arrow appears on the black puck (test charge) showing the force the negative charge exerts on the puck.
Question 1
Part A
Place a red charge on the hockey field and click Play. In which direction do electric field lines point? In which direction does the black puck move? What conclusion do you draw from this movement?
Part B
Click Reset and then click Clear. Now, place a blue charge in the hockey field and click Play. In which direction do electric field lines point? In which direction does the black puck move? What conclusion do you draw from this movement?
Part C
Manipulate the mass of the puck by dragging the mass bar to the right to increase the mass and to the left to decrease it. What changes do you see in the speed of the puck? Which principle works behind this change?
Part D
In the same situation, what do you observe about the relationship between the speed of the black puck and its distance from the blue charge?
Question 2
You can make the puck travel in complex ways by placing a set of charges around on the field. So, here’s your game challenge: Arrange sources charge around to propel the puck from its starting position into the goal. That’s pretty easy for a straight shot; you just put a negative charge behind the goal. But what if there are barriers along the way? This is a real test of your physical understanding, including Newton’s laws of motion and electrostatic forces. Game’s on!
Part A
On the control bar, check the Trace and Field boxes. The game has three Difficulty levels. Start with Difficulty level one and arrange source charges to get the puck into the goal. Once you’ve made a score at any level, increase the Difficulty level. Take a screen capture of two of your most difficult goals and paste them here. At least one of these should be at Difficulty level 2 or 3.

Answer:
The positive charges point away from each other
Explanation:
Why?
Arrows point away from the positive charge and toward the
negative charge.
Explanation:
Suppose that you rubbed a balloon with a sample of animal fur such as a wool sweater or even your own hair. The balloon would likely become charged and its charge would exert a strange influence upon other objects in its vicinity. If some small bits of paper were placed upon a table and the balloon were brought near and held above the paper bits, then the presence of the charged balloon might create a sufficient attraction for the paper bits to raise them off the table. This influence - known as an electric force - occurs even when the charged balloon is held some distance away from the paper bits. The electric force is a non-contact force. Any charged object can exert this force upon other objects - both charged and uncharged objects. One goal of this unit of The Physics Classroom is to understand the nature of the electric force. In this part of Lesson 1, two simple and fundamental statements will be made and explained about the nature of the electric force.
Perhaps you have heard it said so many times that it sounds like a cliché.
Opposites attract. And likes repel.
These two fundamental principles of charge interactions will be used throughout the unit to explain the vast array of static electricity phenomena. As mentioned in the previous section of Lesson 1, there are two types of electrically charged objects - those that contain more protons than electrons and are said to be positively charged and those that contain less protons than electrons and are said to be negatively charged. These two types of electrical charges - positive and negative - are said to be opposite types of charge. And consistent with our fundamental principle of charge interaction, a positively charged object will attract a negatively charged object. Oppositely charged objects will exert an attractive influence upon each other. In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object. This repulsive force will push the two objects apart. Similarly, a negatively charged object will exert a repulsive force upon a second negatively charged object. Objects with like charge repel each other.

The net force acting on this object is 200N to the left. What is the force of friction and air resistance combined if the thrust force is 500N?
Answers
Answer:
Explanation:
Force of friction and air resistance acts against the external force . Let it be f .
net force = external force - frictional force and air resistance
Putting the given values
200 = 500 - f
f = 500 - 200 = 300 N .
Hence force of friction = 300 N .

following represents a possible value for the force of static friction when
Jamie applied 75.1 Newtons of force on the box? (**hint- you do not need
to do math for this problem) *
A. 71.9 N
B. 75.1 N
C. 85.3 N
D. 133 N
Answers
A possible value for the force of static friction when Jamie applied 75.1 Newtons of force on the box is 75.1N. Option B is correct.
For the box sitting on a horizontal surface, the formula for calculating the force on the box along the horizontal based on Newton's law is expressed as;
[tex]\sum F_x=ma_x[/tex]Since the forces acting along the horizontal are the frictional force and moving force, the formula above will become;
[tex]F_m-F_f=ma_x[/tex]Since the body is static, hence [tex]a_x=0m/s^2[/tex], the equation becomes;
[tex]F_m-F_f=m(0)\\F_m-F_f=0\\F_m=F_f[/tex]Given the force Jamie apply on the box to be 75.1Newtons, this shows that the moving force is 75.1N. Hence;
[tex]F_m =F_f=75.1N[/tex]Hence a possible value for the force of static friction when Jamie applied 75.1 Newtons of force on the box is 75.1N

12. In which of the positions shown in the picture, will Joshua have both potential and kinetic energy?
Answers
Answer:
Answer: D. Only R
Explanation:
The Principle Of Conservation Of Mechanical Energy
In the absence of friction, the total mechanical energy is conserved. That means that
Em=U+K is constant, being U the potential energy and K the kinetic energy.
At the top of the path (point Q), Joshua is at rest but his height is at a maximum. Thus his kinetic energy is zero.
At point P, Joshua is at the minimum level (potential energy zero) and his speed is at a maximum.
At point R, Joshua has some height and some speed which means he has both types of energy.
