F=m∙a
m, mass = 8,000 kg
a, accelerating rate = 4 m/s2
F=8000*4
=32000 kg m/s2
=32000 N
Answer:
Elephant
Explanation:
has a larger mass which equates to greater momentum
Answer:
400 N
Explanation:
From the question,
F = kmm'/r²........................ Equation 1
Where F = gravitation force, m and m' = mass 1 and mass 2 respectively, r = distance between the masses.
Given; F = 800 N
Substitute these values into equation 1
800 = kmm'/r².............. Equation 2
If the distance is doubled (2r), and one of the mass is doubled (2m), The new force is
F' = k(2m)(m')/(2r)²
F' = 2kmm'/4r²
F' = kmm'/2r²................. Equation 3
Comparing equation 2 and equation 3
F' = F/2............................ Equation 4
Substitute the value of F into equation 4
F' = 800/2
F' = 400 N
Answer:
alpha radiation
Explanation:
e ) Alpha particles can not be detected outside body as it can not penetrate the layer of skin of our body .
So correct answer is "alpha radiation" .
Explanation:
the electrostatic force is also known as the coulomb force or coulomb interaction. it's the attractive or repulsive force between two electrically charged object. like charges repel each other while unlike charges attract each other. coulomb's law is used to calculate the strength of the force between two charger .
