Answer:
cryosphere is all those areas of earth where the surface is frozen while hydrosphere is all waters of earth, as distinguished from the land and the gasses of the atmosphere
Answer:
The acceleration is 4, 8 m/s2
Explanation:
We calculate the acceleration, with the data of mass and force, through the formula:
F= m x a ---> a= F/m
a= 435 N/90 kg 1N= 1 kg x m/s2
a= 435 kg x m/s2/ 90 kg
a= 4,8 m/s2
Answer:
Explanation:
The magnetic force between two current-carrying wires is given by:
where
is the vacuum permeability
I1 and I2 are the two currents
r is the distance between the wires
Here we have:
Substituting into the equation,
Answer:
m = 0.59 kg.
Explanation:
First, we need to find the relation between the frequency and mass on a spring.
The Hooke's law states that
And Newton's Second Law also states that
Combining two equations yields
The term that determines the proportionality between acceleration and position is defined as angular frequency, ω.
And given that ω = 2πf
the relation between frequency and mass becomes
.
Let's apply this to the variables in the question.
