Answer:
Mechanical Energy as the Ability to Do Work An object that possesses mechanical energy is able to do work. In fact mechanical energy is often defined as the ability to do work. Any object that possesses mechanical energy.
Explanation:
Answer:
m = 12.05 kg
Explanation:
Spring constant in K, N/m
K = 200/10* 100
K = 2000 N/m
Angular Frequency = sqrt (Spring constant / (Mass )
ω = 2 π f
ω = 2π* 2.05 Hz = 12.8805 rad/s
ω^2 = Spring constant / Mass
Mass= Spring constant / ω^2
ω^2 = 165.907 rad^2/s^2
m = 2000 (N/m)/165.907 (rad^2/s^2)
m = 12.05 kg
Answer:
False
Explanation:
The mass of an object is normally known as the weight of the object. but mass is the amount of matter in the object. Weight is the force exerted on an object by gravity
The correct answer is C. Plug in x and y value for answers to see if they work. For example, 9/3 = 3. So C is the answer.
Answer:
4.5 Nm (Anticlockwise)
Explanation:
Let the 75 kg kid is sitting at the left end and the 60 kg kid is sitting on the right end.
Anticlockwise Torque = 75 x 1.5 = 112.5 Nm
clockwise Torque = 60 x 1.8 = 108 Nm
Net torque = Anticlockwise torque - clockwise torque
Net Torque = 112.5 - 108 = 4.5 Nm (Anticlockwise)
