help plss .. Two bicyclists are accelerating forward in a straight line, and Biker 1 has less
mass than Biker 2. If the net force on the bikers is the same, which statement
describes their acceleration?

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.

Hmm lets see.. I think its

Mechanical---->Mechanical---->Electrical

So mechanical from the water, Then mechanical again from the wheel then through the wire which is electrical and it turns the fan on.

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".

a. 178.5 m

b. 69.97 m/s

c. 7.14 s

Given

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 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;

Since the forces acting along the horizontal are the frictional force and moving force, the formula above will become;

Since the body is static, hence [tex]a_x=0m/s^2[/tex], the equation becomes;

Given the force Jamie apply on the box to be 75.1Newtons, this shows that the moving force is 75.1N. Hence;

Hence a possible value for the force of static friction when  Jamie applied 75.1 Newtons of force on the box is 75.1N

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 .

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.

Answer: D. Only R

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).

Answer:

The net force is zero.

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.
