A 3 Kg ball at the end of a string is spun in a circle. If the length of the string is 2 m and the velocity of the ball is 6 m/s

gulaghasi [49]

M is 3kg
r is 2m
v is 6m/s

Fc = mv^2 / r
Fc = (3x6^2)/2 =54

a = v^2/r
a = 6^2 /2 = 18

You use 350 W of power to move a 7.0 N object 5 m.<br> How long did it take?

PilotLPTM [1.2K]

Answer:

0.1 second

Explanation:

We are given;

Power; P = 350 W

Force; F = 7 N

Distance; d = 5 m

Formula for power is;

P = workdone/time taken

Workdone = F × d

Thus;

350 = (7 × 5)/t

t = 35/350

t = 0.1 second

Define the term Distance.

Aloiza [94]

Distance is defined as the space between two points in space.

<h3>What is distance?</h3>

Distance is defined as the space between two points in space.

The unit of distance is metres or kilometres.

Distance can be measured directly usind instruments such as metre rule and tape rule.

The formula for calculating distance is given below:

Distnce = velocity × time.

Therefore, distance is defined as the space between two points in space.

when earth and moon are separated by a distance of 3.84×10^8 meters, the magnitude of the gravitational force of attraction betw

sammy [17]

The gravitational force would be $8\cdot 10^{20} N$

Explanation:

The magnitude of the gravitational force between two objects is given by

$F=G\frac{m_1 m_2}{r^2}$

where

$G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2}$ is the gravitational constant

m1, m2 are the masses of the two objects

r is the separation between them

In this case, we can write the gravitational force between the Moon and the Earth as:

$F=G\frac{M m}{r^2}$

where M is the Earth's mass and m is the Moon's mass.

We know that:

$r=3.84\cdot 10^8 m$ is their separation

$F=2.0 \cdot 10^{20}N$ is the force between them

So we can find:

$GMm = Fr^2 = (2.0\cdot 10^{20})(3.84\cdot 10^8)^2=2.95\cdot 10^{37} Nm^2$

Now, we are asked to find the gravitational force when the Earth and the Moon are separated by

$r'=1.92\cdot 10^8 m$

In this case the new force would be

$F'=G\frac{M m}{r'^2}$

And substituting the values of (GMm) found previously and r', we find

$F'=\frac{2.95\cdot 10^{37}}{(1.92\cdot 10^8)^2}=8\cdot 10^{20} N$
