Answer:
24° north of east
Explanation:
tan(x)=90/200 ie x=arctan(90/200)=24°
So the plane took off 24° east.

The use of force to move an object is
.
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
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).
Why can't a distance/time graph be used to find an object's velocity?

Will the sun explode in future?
Answer:
Explanation:
The Sun won't explode. ... Eventually (in five or seven billion years time), the Sun's life will come to an end. Our star will swell up, becoming something called a “Red Giant” star. It might even get so big that it swallows the Earth whole.

Which is NOT considered as a property of electromagnetic waves: 5
- Travels at speed of 3 x 10^8 m/s
- Transverse wave
- Transfer energy /information
- Require a medium to propogate
Answer:
require a medium to propagate
Explanation:
this is because electromagnetic waves can travel through vacuum at the speed of 3.0 x 10^8 m/s
because they don't need particles to transfer energy

Which of the following is an example of an electromagnet?
A. The magnets used to lift metal or cars in a salvage/junk yard
B. the bar magnets we used in the lab
C.the magnets used to hold pictures on a refrigerator or papers on a metal filing cabinet
Answer:
A. The magnets used to lift metal or cars in a salvage/junk yard
Explanation:
An electromagnet is defined as a type of magnet which are made up of wires in coil shape. Magnetic field in these wires are produced by electric current.
An example of an electromagnet is magnets used to lift metal or cars in a salvage/junk yard because a crane is used in junkyard to lift metal in which crane is attached to a iron disc and when electricity is off, the disc move downwards and placed near required metal and switch on the electricity when disc reaches on metal or cars to be lifted. This electricity generates magnetism in the iron disc and attract metal or cars from the junkyard.
Hence, the correct answer is "A. The magnets used to lift metal or cars in a salvage/junk yard".
how many electrons does a neutral atom of the element iron (fe) have?

When water waves meet, they can combine to form new waves. In constructive waves, a ________ amplitude wave is formed. In destructive waves, a wave with a __________ amplitude is formed. A) greater, smaller B) smaller, greater C) smaller, smaller D) greater, greater
Answer:
In constructive waves, a greater amplitude wave is formed. In destructive waves, a wave with a smaller amplitude is formed. (option A)
Explanation:
Interference is called the superposition or sum of two or more waves. Depending mainly on the wavelengths, amplitudes and the relative distance between them, there are two types of interference: constructive or destructive.
Constructive interference occurs when there are two waves of identical or similar frequency (both have motions equal to an even number of similar wavelengths) and overlap the peak of one with the peak of the other. These effects add together and make a wave of greater amplitude. All of this is possible because the waves were in the same phase in the beginning (in the same position).
Destructive interference occurs in the opposite case to constructive. When the crest of one wave overlaps the valley of the other, they cancel out since they are in different phases when they overlap (they were in different positions). That is, as in the case of constructive waves they were added, in the case of destructive waves they cancel out (subtract).
So, In constructive waves, a greater amplitude wave is formed. In destructive waves, a wave with a smaller amplitude is formed.

Which of the following is NOT a example
of a chemical change?
A. an egg being cooked
B. a piece of paper being torn
C. a piece of bread being toasted
Answer:
B. a piece of paper being torn
Explanation:
A chemical change is one that cannot be reversed. This means the original properties of the substance or object cannot be restored.
If you cook a raw egg, it would turn into a boiled egg (or a poached egg, however it is being cooked). The reaction is irreversible, so you cannot turn the cooked egg back into a raw egg - it is basically impossible to 'uncook' an already cooked egg.
When you toast a piece of bread, it turns into toast. You can't 'untoast' it back into bread. The chemical changes have already occurred and cannot be undone.
If you tear a piece of paper, it is still paper. You are only ripping it, not changing anything about it. You could simply tape the torn bit back to the original bit, or glue it - either way, it is still paper and nothing has occurred to drastically change the physical state of it.
Therefore, B is not a chemical change.

A projectile is sitting on top of a cliff that is 250m above ground. The projectile is
launched with a horizontal speed of 25m/s
(a) How far from the base of the cliff did the projectile “land?”
(b) What is the vertical speed of the projectile when it lands [just before it hits
the ground]?
(c) How long did it take the projectile to reach the ground?
a. 178.5 m
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
vy = voy + gt(voy=0)
vy = 9.8 x 7.14
vy = 69.97 m/s

A 61.0 kg box is sitting at rest. In order to change the box's state of
motion, Jamie must apply 75.1 Newtons of force on the box. Which of the
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
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
