Work = Force * distance
He's going up an incline but pushing parallel to the ground. Draw out a diagram to show what's going on. )
Work = force* distance*Cos(incline angle)
60 N force * 10 meters * cos(30)
= 519.61 J
Answer:
The natural frequency = 50 rad/s = 7.96 Hz
Damping ratio = 0.5
Explanation:
The natural frequency is calculated in this manner
w = √(k/m)
k = spring constant = 5 N/m
m = mass = 2 g = 0.002 kg
w = √(5/0.002) = 50 rad/s
w = 2πf
50 = 2πf
f = 50/(2π) = 7.96 Hz
Damping ratio = c/[2√(mk)] = 0.1/(2 × √(5 × 0.002)) = 0.5
Answer:
Explanation:
We are not told where A and B are, but I'll assume that they are two points on the orbit of earth about the sun.
As that orbit is an ellipse, the two points likely do not have the same distance between the earth and sun.
As gravity varies with the inverse of the square of the distance (F = GMm/d²), the force at the closer distance will be greater than the force at the longer distance.
Answer:
Heat, Let me explain,
Explanation:
An exothermic reaction is like... Lighting a candle so it produces a small amount of heat in less than a second and then normal heat.
Answer:
D) 10 200 m
Explanation:
Speed is known as the rate of change of distance.
distance = speed * time
= 85 ms⁻¹ * 120 s
= 10200 m
