Answer:
70.035nN
Explanation:
M₁ = 7.0kg
m₂ = 1.5kg
r = 0.1m
G = 6.67*10⁻¹¹ Nm²/kg
Gravitational force (F) of an object is directly proportional to the product masses and inversely proportional to the square of their distance apart.
F = GM₁M₂ / r²
F = (6.67*10^-11 * 7.0 * 1.5) / (0.1)²
F = 7.0035*10^-10 / 0.01
F = 7.0035 * 10^-8 N
F = 70.035nN
The gravitational force acting on the bowling ball is 70.035nN.
Answer:
erm they all should have same numbers of protons
Answer : The kinetic energy depends directly on the mass of a particle.
Explanation :
We know that the kinetic energy of any particle is given by :

Where,
m is the mass of an object.
v is the velocity with which it is moving
Kinetic energy is due to the motion of the particle.
So, the kinetic energy of a particle is directly proportional to its mass.
Hence, the conclusion of the question is if the mass of a particle is increases then its kinetic energy also increase.
Answer:
The frictional force is 
Explanation:
From the question we are told that
The coefficient of kinetic force is μk = 0.35
The normal force felt by the puck is 
Generally the frictional force that acts on the puck is mathematically represented as

=> 
=> 
<h2>
Answer: It is highly flammable.</h2>
Explanation:
Liquid oxygen is created from oxygen atoms that have been forced to assume the liquid state due to <u>compression (change of pressure) and temperature modification.
</u>
Specifically this is achieved by cooling the oxygen enough to change it to its liquid state. So,<u> as the temperature drops, the atoms move more slowly because they have less energy.
</u>
In this sense, in the liquid state it is easier to store and mobilize oxygen, taking into account that it is a highly flammable gas.
