Answer:

= 54,000 Joules or 54 kJ

Explanation:

Electrical energy is given by the formula;

E = VIt; where V is the potential difference in volts, I is the current and t is the time in seconds.

Therefore;

Electrical energy = 120 V × 0.50 A × 15 ×60 seconds

                            = 54,000 Joules

Thus; the electrical energy is 54,000 joules or 54 kJ

The pressure exerted by a liquid column of depth 0.5 m on the base of its
Alik [6]

Answer:

1020.4kg/m³

35m³

Explanation:

Given parameters:

Depth  = 0.5m

Pressure exerted  = 5000N/m²

Unknown = density of the liquid  = ?

Solution:

To find the density of this unknown liquid, we use the expression below:

       Pressure of liquid  = density x height x acceleration due to gravity

   5000 = density x 0.5 x 9.8

    Density  = 1020.4kg/m³

B.

Density of water  = 1000kg/m³

Mass of water  = 35000kg  

 Unknown:

Volume of water  = ?

Solution:

 The volume of water can be derived from the expression below:

   Volume  = \frac{mass}{density}  

  Volume  = \frac{35000}{1000}    = 35m³

1. How much force would you have to apply to a 15kg object in order to accelerate it!<br> a 2 m/s?
mihalych1998 [28]

30N

Explanation:

Given parameters:

Mass of object = 15kg

Acceleration = 2m/s

Unknown:

Force = ?

Solution:

Force is given as the product of mass and acceleration:

         F = m x a

   m is the mass

    a is the acceleration

Inputting the parameters:

     F = 15 x 2 = 30N

The unit of force is newtons, N .

Alex
I think the corect answer would be C. When a police officer receives information that you are speeding in your vehicle, she is using the frequency of the wave to measure the Doppler Effect. As the speed of a vehicle increases, the greater the change of the frequency of the waves would be transmitted to the radar guns which is being used by the police officer. Doppler effect is an effect that is observed in sound and light waves as these waves move away or to the direction of the observer. This is being used in many applications like in astronomy, weather balloons, the radar guns,and for underwater researches.
