Answer:
12N
Explanation:
Force acting on any body is equal to mass of body multiplied by acceleration produced in the body.
Its formula is
F = M*a
where F is the force acting on body
M is the mass of the body
a is the acceleration produced in the body
Unit of force is Newton represented by N
1 N is force acting on body of mass 1 kg which produces acceleration of 1m/s^2.
_____________________________________
Given
a = 0.50 m/s^2
M = 24 kg
therefore
F = 24*0.5 = 12 N
Thus, magnitude of the boy's pushing force is 12 N.
Answer:
Force to stretch the wire is 250 N
Explanation:
As we know that modulus of elasticity will remain the same for the wire if the applied stretch to the wire is within elastic limit
So we will have

now we have

so we can write it as



-- Since it's a cube, its length, width, and height are all the same 4 cm .
-- Its volume is (length x width x height) = 64 cm³ .
-- Density = (mass) / (volume)
= (176 g) / (64 cm³)
= 2.75 gm/cm³ .
The Big Bang theory is matter and energy in the universe exploded out from one point. As the explosion occurred, energy and matter spread outward and formed the universe. The matter from the Big Bang formed clouds of gas.
