Answer:

F = 30 N Directed up

Explanation:

We can solve this problem using the momentum and momentum relationship.

I = ΔP

I = ∫ F dt

As we are asked for the average force, that leaves the integral, giving

I = F t

F t = m $v_{f}$ - m v₀

F = m ( $v_{f}$ -v₀) / t

Note that, if you define the upward positive direction, the initial velocity is negative

Let's calculate

F = 0.15 (3.5 - (-6.5)) / 0.050

F = 30 N

This was kinda hard thinking it might be that the new force is going to 4 times bigger than the original one.

A piece of plastic has a net charge of +9.9 μC. How many more protons than electrons does this piece of plastic have? (e = 1.60

Leto [7]

Answer:

The number of protons 6.19 more than electron.

Explanation:

Given that,

Charge $Q=+9.9\times10^{-6}\ C$

We know that,

formula of charge

$Q = nc$

Where,

Q = total charge

n = number of protons

e = charge of electron

Put the value into the formula

$n = \dfrac{Q}{e}$

$n=\dfrac{9.9\times10^{-6}}{1.6\times10^{-19}}$

$n=6.1875\times10^{13}\ C$

According to statement of question

Divide the answer by $10^{13}$

$n=\dfrac{6.1875\times10^{13}}{10^{13}}$

$n=6.19\ C$

Hence, The number of protons 6.19 more than electron.

What happens to heat energy after an object is cooled down lolololol asking for my bff

alisha [4.7K]

Answer:

Heat energy does not cool. Objects cool. Energy is not an object. Now, what happens when an object cools is that it gives off some of its thermal energy by one or more mechanisms: radiation, conduction, or convection. In radiation the energy escaped the object as electromagnetic waves - you see the red hot poker slowly dim as it cools, in conduction the energy is transferred Mechanically by the atoms of the hot object being in physical contact with those of the cool object and in convection the hot material moves to a cooler region where it gives up its heat energy by either radiation or conduction.

A projectile of mass m is fired straight upward from the surface of an airless planet of radius R and mass M with an initial spe

motikmotik

Answer:

K = G Mm / 9R

Explanation:

Expression for escape velocity V_e = $\sqrt{\frac{2GM}{R} }$

Kinetic energy at the surface = 1/2 m V_e ²

= 1/2 x m x 2GM/R

GMm/R

Potential energy at the surface

= - GMm/R

Total energy = 0

At height 9R ( 8R from the surface )

potential energy

= - G Mm / 9R

Kinetic energy = K

Total energy will be zero according to law of conservation of mechanical energy

K - G Mm / 9R = 0

K = G Mm / 9R
