gold density = 38.6 *10^-3 / 2 *10^-6 = 19300 Kg/m3
Iron density = 46.8 *10^-3 / 6 *10^-6 = 7800 Kg/m3
water mass = density*volume = 1 * 10 = 10 grams = 0.01 Kg
Answer:
Mechanical energy
Explanation:
Mechanical energy is needed for movement of objects. Muscles convert chemical energy provided by the rest of the body to allow movement.
The differences in energy released by earthquakes are too large to express with linear scales.
Answer:
Explanation:
It is given that,
Mass of bundle of shingles, m = 10 kg
Upward acceleration of the shingles, 
The radius of the motor of the pulley, r = 0.17 m
Let T is the tension acting on the shingles when it is lifted up. It can be calculated as :
T = 113 N
Let 
is the minimum torque that the motor must be able to provide. It is given by :
So, the minimum value of torque is 19.21 N-m. Hence, this is the required solution.
Answer:
Each side of your brain contains four lobes. The frontal lobe is important for cognitive functions and control of voluntary movement or activity. The parietal lobe processes information about temperature, taste, touch and movement, while the occipital lobe is primarily responsible for vision.
