2. A 4-kg gun shoots a 0.1-kg bullet at 400 m/s. Find the recoil speed of the gun.

aliya0001 [1]

Answer:10m/s

Explanation:

M=mass of gun=4kg

U=recoil velocity of gun

m=mass of bullet=0.1kg

V=velocity of bullet=400m/s

M x U=m x V

4 x U=0.1 x 400

4xU=40

Divide both sides by 4

(4xU)/4=40/4

U=10m/s

Recoil velocity=10m/s

In the electric current flow, it is found that the resistance (measured in the units called ohms) offered by a fixed length of w

Likurg_2 [28]

Here's your explanation:
R = k / d^2 (k is a constant, unknown)
d1 = 0.01 and R1 = 0.306
d2 = 0.0299 R2 = ?

Use the equation in line 1 for both case and divide and k will go away and you can find R2

A 5.0 A current is set up in a circuit for 6.0 min by a rechargeable battery with a 6.0 V emf. By how much is the chemical energ

Andre45 [30]

Answer:

The chemical energy of the battery was reduced in 10800J

Explanation:

The first thing to take into account is that the stored energy in a battery is in Watts per second or Joules ( $W\cdot s=J$ ). It means that the battery provides a power for a certain time.

The idea is to know how much $W\cdot s$ has been consumed by the circuit.

The first step is to know the power that is consumed by the circuit. It is $P=V\cdot I$ . The problem says that the circuit consumes a current of 5.0A with a voltage of 6.0V. It means that the power consumed is:

$P=V\cdot I=(6.0V)\cdot (5.0A)=30W$

The previous value (30W) is the power that the circuit consumes.

Now, you must find the total amount of power that is consumed by the circuit in 6.0 minutes. You just have to multiply the power that the circuit consumed by the time it worked, it means, 6.0 minutes.

$energy=P\cdot t=(30W)\cdot (6.0min)=180W\cdot min$

You must convert the minutes unit to seconds. Remember that 1 minute has 60 seconds.

$energy=P\cdot t=(30W)\cdot (6.0min) \cdot \frac{60s}{1min}=10800W\cdot s=10800J$

Thus, the chemical energy of the battery was reduced in 10800J
