Answer:
<h2>103 Joules</h2>
Explanation:
In this problem we are required to find the potential energy possessed by the television
Given data
mass of television m = 15 kg
height added above the ground, h= 1-0.3 = 0.7 m
acceleration due to gravity g = 9.81 m/s^2
apply the formula for potential energy we have
P.E= m*g*h
P.E = 15*9.81*0.7 = 103 Joules
Answer:
The acceleration of the elephant is 5m/s^2 (squared).
Explanation:
Given: Force=200N, Mass=1000kg
Required: acceleration=?
Equation: a=F/m
Solution: a=200N/1000kg
Answer: a=5m/s^2
Answer:
30°
Explanation:
<em>The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.</em>
∠i = ∠r
so as ∠i = 30°
∠r will also be 30°
Answer:
R=2F
Explanation:
As the forces are in same direction so the resultant force will be:
R=F+F
R=2F
Yes I would expect them too
