Two students are sitting 1.50 m apart. One student has a mass of 70.0 kg and the other has a mass of 52.0 kg. What is the gravit

algol [13]

Answer:

The gravitational force between them is $1.079\times10^{-7}\ N$ .

Explanation:

Given that,

Distance = 1.50 m

Mass of one student = 70.0 kg

Mass of other student = 52.0 kg

We need to calculate the gravitational force

Using formula of gravitational force

$F=\dfrac{Gm_{1}m_{2}}{r^2}$

Where, m₁ = mass of one student

m₂ = mass of other studen

r = distance between them

Put the value into the formula

$F=\dfrac{6.67\times10^{-11}\times70.0\times52.0}{1.50^2}$

$F=1.079\times10^{-7}\ N$

Hence, The gravitational force between them is $1.079\times10^{-7}\ N$ .

A car travelling at 15 m/s comes to rest in a distance of 14 m when the brakes are applied.

stira [4]

Answer:

-8.04 m/s2

Explanation:

To find the answer to this, you have to use the 4th kinematic equation:

$v^{2} = v^{2}_{0} + 2ax$

You plug into the equation to get:

$0 = 15^{2} + 2a(14)$

solve for a to get

-8.04 m/s2

Volume of an block is 5 cm3. If the density of the block is 250 g/cm3, what is the mass of the block ?

wlad13 [49]

Answer:

The mass of the block is 1250g.

Explanation:

Given that the formula for density is ρ = mass/volume. Then you have to substitute the values into the formula :

$ρ = \frac{mass}{volume}$

Let density = 250,

Let volume = 5,

$250 = \frac{m}{5}$

$m = 250 \times 5$

$m = 1250g$
