a wagon weighing 1800 newtons is pulled by a horse at a speed of 0.40 m/sec. what is the power of this horse?
adelina 88 [10]
Power is equal to (Newtons x meters)/time, also known as the following equation...

P = Fd/t

Your force is 1800Newtons and your velocity is 0.4m/s
Velocity is equal to distance/time, also known as the following equation...

v = d/t

So your equation is basically P = Fv

P = 1800N x 0.4m/s

P = 720 Watts

If the density of a diamond is 3.5 /cm^ 3 what would be the mass of a diamond whose volume is 0.5 cm ^ 3 ?
Elan Coil [88]

Answer:

1.75g

Explanation:

Given parameters:

Density  = 3.5g/cm³

Volume  = 0.5cm³  

Unknown:

Mass of the diamond  = ?

Solution:

Density is the mass per unit volume of a substance

  Density  = \frac{mass}{volume}  

So;

  Mass  = 3.5 x 0.5  = 1.75g
