The answer is D. Run only full loads in the washing machine and dishwasher.

B doesn't seem like a good idea, C uses more water, and A would save water but not as much as the washing machine and dishwater use.

Answer:

Option D

Explanation:

It has been observed that when a dishwasher or a washing machine is not used at its full load, then approximately thirty gallons of water per wash goes waste due to non-usage or non- optimized usage. However, in case when these two machines are fully loaded, the 30 gallons of water per wash is also utilized to its full extent. In case if there are not enough utensils or clothes to fully load the machine, it would be advisable to manually clean the dishes and clothes.  

Closing the tap while brushing also saves water. Per brushing nearly 3 gallons of water can be saved.  

Hence, option D would save the maximum water.

terry physics pushes a 75kg lab cart so that is accelerates from rest with a velocity of 4.4m/s in 3.1 secounds. what is the for
svetlana [45]

106.5N

Explanation:

Given parameters:

Mass of cart = 75kg

Velocity = 4.4m/s

time taken = 3.1s

Unknown:

Force = ?

Solution:

To solve this problem, we are going to apply newton's second law of motion. The law states that "the acceleration of a body is directly proportional to the force on the body and inversely proportional to the mass".

      F = m  x   a

F = force on body

m = mass of body

a = acceleration of the body

 But we know that acceleration is the change in velocity with time of a body;

     a  = \frac{change in velocity }{time}

  F = m x \frac{V}{t}

V is the velocity

t is the time taken

   F = \frac{75  x  4.4}{3.1}   = 106.5N
