Question

help plzzzzzzzzzz !!!!!!​

Answer 1

$\bigstar$ Given:-

→ Force = 5 N

→ Distance = 20 m

→ Time = 30 s

$\bigstar$ To Find:-

→ Power

$\bigstar$ Solution:-

We know that

$\star$ Power

$\red{\rm \longrightarrow P=\dfrac{W}{t}}$

$\star$ Work done

$\orange{\rm \longrightarrow W=Fd}$

Combining both

We get:-

$\pink{\rm \longrightarrow P=\dfrac{Fd}{t}}$

Here:-

P = Power

F = Force

d = Distance

t = Time

Units:-

P = Wattage (W)

F = Newton (N)

d = metre (m)

t = second (s)

According to the question:

We are asked to find the power;

Therefore:-

We must find " P "

Given that

→ Force = 5 N

→ Distance = 20 m

→ Time = 30 s

Hence

F = 5 N

d = 20 m

t = 30 s

Substituting the values

We get;

$\rm \longrightarrow P=\dfrac{5 \times 20}{30} \ W$

$\rm \longrightarrow P=\dfrac{100}{30} \ W$

$\rm \longrightarrow P=\dfrac{10}{3} \ W$

Therefore

$\purple{\rm \longrightarrow P=3.33 \ W}$

Hence:

$\checkmark$ Power = 3.33 W

Answer 2

Answer:

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \huge\bf\underbrace{{\blue { Aиѕwєя}}} \: \dag$

3.33 Joules Per Second

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \large \sf{Explanation:}$

Before finding the Power, we need to calculate the Work Done. The Work Done can be calculated using the formula:

$\sf{WD = F × d}$

where F is the Magnitude of Force in N

d is the Parallel Distance moved by the object in m.

Hence, by Applying this formula, we get:

$\sf{WD = (5)(20)= 100 J}$

From here calculating Power is simple as it is the Rate of Work Done. Hence,

$\sf{Power = 100/30= 3.33 J/s}$

$\sf{Therefore, the \: power \: put \: out \: is \: 3.33 \: Joules \: per \: Second.}$
