According to Galileo, this quantity is not needed to keep a body in motion under ideal conditions.

This condition is called Galileo's Law of Inertia which states that all bodies accelerate at the smart rate , no matter what are their masses or size. Inertia is that tendency of matter to resist changes in its velocity. <span>Isaac Newton's first law of motion captures the concept of inertia. </span>

Answer:

According to Galileo, quantity does not matter under ideal conditions. The ideal conditions to experiment under is when there is no air resistance only then it can be seen that the statement is true i.e. quantity is not a factor

If you drop a ball and a feather under the ideal condition i.e. no air resistance you will see that both the ball and feather which weigh different will fall at the same time

Answer:d

Explanation:

All the given situations are possible because

(a)When particles are oppositely charged then they attract each other

(b)One is Positively charged and other is uncharged: Charged particle will induce charges of opposite nature to attract the other particle

(c)Negatively charged particles will induce the positive charge in the uncharged particle to attract the initially uncharged particle.

A 3 kg bowling ball is thrown onto a mattress. If it takes 0.3 seconds to stop the ball using a force of 24 N, what was the init

Lubov Fominskaja [6]

Answer:

2.4 m/s

Explanation:

Applying Newton's second law of motion,

F = m(v-u)/t.............. Equation 1

Where F = force exerted on the ball, m = mass of the ball, v = final velocity of the ball, u = initial velocity of the ball, t = time required to stop the ball.

Note: Since the the ball come to stop, then v = 0 m/s.

F = -mu/t............. Equation 2

make u the subject of the equation

u = -Ft/m............. Equation 3

Given: m = 3 kg, t = 0.3 s, F = 24 N

Substitute into equation 3

u = -(24×0.3)/3

u = -2.4 m/s.

Note the negative sign tells that the initial velocity of the ball is in opposite direction to the force acting on the ball.

Dafna11 [192]

Hey there!

They should rise at the same height if there is no friction and they are moving at a constant speed regardless of weight.

Hope this helped, have a good one.

What is Hope's apparatus ?

mote1985 [20]

Hope's apparatus is a glass cylinder encircled with a trough half-way up to contain a freezing mixture. Holes in the cylinder at the top and the bottom allow thermometers to be inserted into the water to sample its temperature.
