Explanation:
mass, m = 5kg
initial velocity, u = 16m/s
final velocuty, v = -22m/s
change in momentum, ∆p = ?
∆p = m (v-u)
5(-22-16)
5(38)
∆p = 190kgm/s
check the calculations!

Sorry - it cannot be done as Brainly does not allow it. If you do not have too many points, you may consider closing this account and opening a new one with another name. Many people have multiple accounts here.
Answer:
Explanation:
The frequency equation is
where f is frequency measured in Hz, v is velocity of sound measured in m/s and
is wavelength measured in meters. Filling in our given info:
and
so
(That is the incorrect number of sig dig's by the way. It should only be 2 since the number 340 only has 2 sig dig's)
force applied due to earth on the apple is given as

given that
m = 0.37 kg
a = 9.8 m/s^2
now we have


now as per Newton's III law equal and opposite force is applied on earth
so now we can find acceleration of Earth using same equation as we used above

here we know that
m = mass of earth
F = 3.63 N



so acceleration of earth is very small and given by above value
