A laptop computer draws 5 A of current with a voltage of 19 V. Which is the power used by the computer?

2 answers:

6 0

There are several information's of importance already given in the question. Based on those information's the answer can be deduced.
Volage = 19 V
Current = 5 A
Power = Voltage x Current
= 19 x 5
= 95 Watt
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the second option or 95 W.

Answer : The power used by the computer is, 95 W

Solution : Given,

Current = 5 Ampere

Voltage = 19 Volt

Power : It is defined as the product of the voltage and the current in the circuit.

Formula used :

$P=V\times I$

where,

P = power

V = voltage

I = current

Now put all the given values in the above formula, we get the power used by the computer.

$P=V\times I=(19V)\times (5A)=95watt=95W$

Therefore, the power used by the computer is, 95 W

A paintball’s mass is 0.0032kg. A typical paintball strikes a target moving at 85.3 m/s.

vekshin1

Answer:

A) If the paintball stops completely the magnitude of the change in the paintball’s momentum is $p=0.273kg*m/s$

B) If the paintball bounces off its target and afterward moves in the opposite direction with the same speed, the change in the paintball’s momentum is $p=0.546kg*m/s$

C) A paintball bouncing off your skin in the opposite direction with the same speed hurts more than a paintball exploding upon your skin because of the strength exerted is twice than if it explodes.

Explanation:

A) We use the formula of momentum $p=mv$ , so we have $p=0.0032kg*85.3m/s=0.273kg*m/s$

B) We use the same formula above, then due we have a change of direction at the same speed, therefore the change in the momentum is the double so

$p=2*0.0032kg*85.3m/s=0.546kg*m/s$ .

C) The average strength of the force an object exerts during impact is determined by the amount the object’s momentum changes. therefore

$F=\frac{\Delta p}{\Delta t}$ , as we don't have any data about the impact time but we know momentum is twice, time does no matter and strength is twice too.
