What is the

Len [333]

Answer:

$d=5\ g/cm^3$

Explanation:

Given that,

Mass of the object, m = 100 grams

Volume of the object, V = 20 cm³

We need to find the density of the object. We know that, density is equal to mass per unit volume. So,

$d=\dfrac{m}{V}\\\\d=\dfrac{100\ g}{20\ cm^3}\\\\d=5\ g/cm^3$

So, the density of the object is equal to $5\ g/cm^3$ .

Muscles use force to move objects. When using a ramp to do work, would your muscles use more force or less force?

Less because the ramp is letting off force but i does depend on the way you are going on the ramp

A hovering mosquito is hit by a raindrop that is 50 times as massive and falling at 8.1 m/s , a typical raindrop speed. how fast

Airida [17]

here we will use the momentum conservation

initial total momentum = final total momentum

$P_i = P_f$

$m_1v_{1i} + m_2v_{2i} = m_1v_{1f} + m_2v_{2f}$

now plug in all data here

$m(0) + 50m(8.1) = mv + 50mv$

$405 = 51 v$

$v = 7.94 m/s$

so the final speed will be 7.94 m/s
