The object will sink in any liquid whose density is less than 0.75 g/mL .
A few examples are butane, ether, gasoline, hexane, octane, naphtha, pentane, and propane.
M = mass of the bowling ball = 4 kg
V = speed of bowling ball = 3.93 m/s
P = magnitude of momentum of bowling ball = ?
magnitude of momentum of bowling ball is given as
P = MV
inserting the values
P = 4 x 3.93
P = 15.72 kgm/s
m = mass of ping-pong ball = 2.293 g = 2.293 x 10⁻³ kg
v = speed of the ping-pong ball = ?
p = magnitude of momentum of ping-pong ball
Given that :
magnitude of momentum of ping-pong ball = magnitude of momentum of bowling ball
p = P
m v = 15.72
(2.293 x 10⁻³) v = 15.72
v = 6.86 x 10³ m/s
Explanation:
The protons determines the atomic number which helps in identifying an atom of an element
A higher frequency. I just got this answer on usa test prep.
Answer:
The value of acceleration due to gravity is independent of mass of the body.
Explanation:
Let us consider the mass of the object as m and mass of earth as M
Therefore, force between the object and earth would be given by: F = GMm/d²
This force is equal to the weight of the object, i.e. mg
Thus;
mg = GMm/d²
g = GM/d²
Therefore, the value of acceleration due to gravity is independent of mass of the body.
