Because acceleration was constant throughout the slide, we can show the slide lasted
Also because accleration was constant, we know the average velocity of the book was
Average velocity is also given by
so the width of the desk must have been
which means C is the most likely answer.
The temperature is the degree on intensity of heat in a specific place. Usually, the temperature of thermic neutrality is 70 Fahrenheit or 21 Celsius.

Answer:
F₁ = F₂
Explanation:
Given that
floor pushing up on you by force F₁
gravity pulling down by force F₂
From second law of Newton's
F₁ - F₂ = m a
But here given that ,elevator is moving with constant speed .It means that acceleration of the elevator is zero.
a= 0 m/s²
F₁ - F₂ = m x 0
F₁ = F₂
Answer:
<h2>2500 N</h2>
Explanation:
The weight of the object can be found by using the formula
w is the workdone
d is the distance
From the question we have
We have the final answer as
<h3>2500 N</h3>
Hope this helps you
Answer:
True
Explanation:
Transmutation is known as the change of substance from one to the other substance by radioactive decays or nuclear reaction process.
The beta decay is the radioactive process in which proton is converted into neutron then there is decrease in proton number this beta decay is called positron emission beta plus decay.
If the neutron is changing into proton which means there is an increase in proton number these decay is called beta minus decay.
Therefore, by the above discussion it can be say that a radioactive decay or can say that nuclear reaction which result in a nuclei with greater than or lesser proton that the initial nuclei is called transmutation.
