Given that,
Voltage = 10 volt
Suppose, The three resistance is connected in parallel and each resistance is 12 Ω. find the current in the electric circuit.
We need to calculate the equivalent resistance
Using formula of parallel

Put the value into the formula



We need to calculate the current in the circuit
Using ohm's law


Where, V = voltage
R = resistance
Put the value into the formula


Hence, The current in the circuit is 2.5 A
3750 seconds to travel that far
Answer:8 meters
Explanation:100cm is a meter
Answer: "B" Changing Position
Great Question!
Explanation: <u><em>When a ball bounces to the ground it hits the ground with some energy. The amount of energy with which it hits the ground is kinetic energy. When it comes in the contact with the ground kinetic energy gets converted into potential energy. This potential energy again gets converted into kinetic energy and balls moves again from the ground and bounces multiple times. So, the ball ends up changing position</em></u>

Answer:
451.13 J/kg.°C
Explanation:
Applying,
Q = cm(t₂-t₁)............... Equation 1
Where Q = Heat, c = specific heat capacity of iron, m = mass of iron, t₂= Final temperature, t₁ = initial temperature.
Make c the subject of the equation
c = Q/m(t₂-t₁).............. Equation 2
From the question,
Given: Q = 1500 J, m = 133 g = 0.113 kg, t₁ = 20 °C, t₂ = 45 °C
Substitute these values into equation 2
c = 1500/[0.133(45-20)]
c = 1500/(0.133×25)
c = 1500/3.325
c = 451.13 J/kg.°C
