The two most common ways are the use of a water restrictor in the shower head, most of the heads in the U.S.A are equipped with a water restrictor. Secondly, the commode water tanks have been made smaller using less water per flush. Some conservation of water may be gained by using "instant" water heaters in the shower/bath and basin rather than a hot water tank type heater. Locating an instant water heater near the output of the water reduces the need to let the water run until it becomes hot at the output. I hope that this is the answer that you were looking for and it has helped you.
"At the bottom, the car has X joules of mechanical energy" is the one among the following choices given in the question that <span>the law of conservation of energy predict about the car. The correct option among all the options that are given in the question is the second option or option "B". I hope the answer helped you.</span>
Answer:
Distance, d = 0.049 meters
Explanation:
It is given that,
Mass of the pile, m = 2500 kg
It is dropped through a height of 8.0 m on each stroke, h = 8 m
The resisting force of the ground,
The work done in each stroke is equal to the potential energy of the pile driver such that,
Work done due to resistive force is :
So,
d is the distance covered by the post driven in on each stroke.
d = 0.049 meters
So, on each stroke the post driven is 0.049 meters far. Hence, this is the required solution.
Answer:
53.36 m.
Explanation:
Initial velocity of the toolbox u = 0
acceleration due to gravity g = 9.8 m s⁻²
time t = 3.3 s
height of roof h = ?
h = ut + 1/2 g t²
= 0 + .5 x 9.8 x 3.3²
= 53.36 m.
Answer:
Magnetic Forces on Moving Charges. The magnetic force on a free moving charge is perpendicular to both the velocity of the charge and the magnetic field with direction given by the right hand rule.
