Answer:
d. all four jovian planets.
Explanation:
The Jovian planets are as follows -
URANUS , SATURN , JUPITER, and NEPTUNE .
All these four jovian planets are having the rings , and the rings are made up of infinite number of small pieces of the ice and the rock .
Hence ,
These planets are comparatively small and dense cores surrounded by massive layers of gas .
Answer:
13 N
Explanation:
From the question,
If two forces act at right angle to each other, Their result force can be calculated using Pythagoras theorem.
R'² = R₁²+R₂²....................... Equation 1
Where R' = Resultant force, R₁ = First force, R₂ = Second force.
Given: R₁ = 12 N, R₂ = 5 N
Substitute these values into equation 1
R'² = 12²+5²
R'² = 144+25
R'² = 169
R' = 
R' = 13 N.
Hence the resultant force is 13 N
Answer:
the correct answer is B
Explanation:
The kinetic model of the movement describes that the movement of the molecules increases with the increase of their internal energy, which in a macroscopic sample is reflected in an increase in the temperature of the sample.
The sample graph shows the function of temperature over time, which is why our kinetic model establishes that there is an increase in the movement of water molecules.
Consequently the correct answer is B
Answer:
30hz is the answer for the question
Answer:
Explanation:
a is the acceleration
μ is the coefficient of friction
Acceleration of the object is given by

Velocity at the bottom

after travelling 4m , its velocity becomes 0



Coefficient of kinetic friction
μ = F/N

Therefore, the Coefficient of kinetic friction is 0.31
