Tom [10]

Answer:

250000kg

Explanation:

Mass =density * volume

Density=1000kg/m³

Volume=l*w*h

12.5*10.0*2.0=250m³

Mass=1000 *250

=250000kg

Why is it that the weight of an object weighing 1N air, weighs more when immersed in water ?
Anni [7]
There is no "why", because that's not what happens.  The truth is
exactly the opposite. 

Whatever the weight of a solid object is in air, that weight will appear
to be LESS when the object is immersed in water.

The object is lifted by a force equal to the weight of the fluid it displaces.
It displaces the same amount of air or water, and any amount of water
weighs more than the same amount of air.  So the force that lifts the
object in water is greater than the force that lifts it in air, and the object
appears to weigh less in the water.

PLEASE HELPP MEEE!!!!!!!!!The goal is to increase the power; therefore, it is necessary to
Brrunno [24]

As we know that power is defined as rate of work done

so we will have

P = \frac{Work}{time}

so in order to increase the power as per above formula we know that either we need to increase the work or we need to decrease the time to complete that work

So here the correct answer will be

increase the work being done or decrease the time in which the work is completed.
