Answer:
Option D
48 N
Explanation:
From Newton's law of motion we deduce that the magnitude of force is a product of mass and acceleration hence expressed as, F=ma where F is the magnitude of force, m is the mass of the object and a is the acceleration of the cart. Substituting 24 kg for m and 2 for acceleration then
F=24*2= 48 N
Answer:
v = 0.92 c
Explanation:
Here, we will use the time dilation formula from Einstein's theory of relativity to find the speed of traveling of the friend:
where,
v = speed of traveling = ?
c = speed of light
t = time of return = 10 years
t₀ = time passed on earth = 4 years
Therefore,
<u>v = 0.92 c</u>
The major shortcoming of Rutherford's model was that it was incomplete. It did not explain how the atom's negatively charged electrons are distrubuted in the space surronding its positively charged nucleus. A form of energy that exhibits wavelike behavior as it travels through space
