Explanation:
Answer:
Explanation:
The work increased the potential energy
W = PE = mgh = 40(9.8)(15) = 5880 J(oules)
Answer:
9.66 x 10^-6 m
Explanation:
Use the Wein's displacement law

Where, b is the Wein's constant
b = 2.898 x 10^-3 meter-kelvin
So, λm x 300 = 2.898 x 10^-3
λm = 9.66 x 10^-6 m

*im pretty sure these are correct if I remember clearly*
Answer:
<h2>2.2 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula

f is the force
m is the mass
From the question we have

We have the final answer as
<h3>2.2 m/s²</h3>
Hope this helps you
