Exertion is not a good way to describe exercise but there is also alot more words to describe wrong ways for exercise
Answer:
(a) The value of the ratio m₁/m₂ is 0.581
(b) the acceleration of the combined masses is 1.139 m/s²
Explanation:
Given;
The acceleration of force applied to M₁, a₁ = 3.10 m/s²
The same force applied to M₂ has acceleration, a₂ = 1.80 m/s²
Let this force = F
According Newton's second law of motion;
F = ma
(a) the value of the ratio m₁/m₂
since the applied force is same in both cases, M₁a₁ = M₂a₂

(b) the acceleration of m₁ and m₂ combined as one object under the action force F
F = ma


Therefore, the acceleration of the combined masses is 1.139 m/s²
Answer:
<h3>The answer is 0.54 m</h3>
Explanation:
The wavelength of a wave can be found by using the formula

where
c is the velocity
f is the frequency
So we have

We have the final answer as
<h3>0.54 m</h3>
Hope this helps you
D. the electron cloud model
(process of elimination: chocolate chip model came way before, planetary and Bohr's are the same and were developed by Niels Bohr)
ANSWER:
250 J
STEP-BY-STEP EXPLANATION:
F = 20N is required to stretch the spring by 4 meters
We know that the force is equal to:

We solve for k (spring constant):

The work done in stretching the spring is given by the following equation (in this case the stretch is 10 meters:

The work required is 250 joules.
