Answer: 0.078
Explanation:
Given variables:
R1 = 25.0 , R2 = 64.0 , I1 = 0.200
Step 1: find V
0.200 = v/25
0.200 * 25 = v
5 = v
Step 2: Solve for I2
I = V/R
I = 5/64
I = 0.078125
Hope this helps!
Answer:
The force on he object can cause an object to move or speed up. It can also make it stop or change direction.
Explanation:
Answer:
Heat energy required = 252000J or 252KJ.
Explanation:
<u>Given the following data;</u>
Mass = 3kg
Temperature = 20ºC
Specific heat capacity of water = 4200 J/kg°C
To find the heat energy required;
Heat capacity is given by the formula;
Where;
- Q represents the heat capacity or quantity of heat.
- m represents the mass of an object.
- c represents the specific heat capacity of water.
- t represents the temperature.
Substituting into the equation, we have;
Q = 252000 Joules or 252 Kilojoules.
