Answer:
<h2>0.67 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
f is the force
m is the mass
From the question we have
We have the final answer as
<h3>0.67 m/s²</h3>
Hope this helps you
A scientific journal article that is peer reviewed. This is because it is more likely not have factual information and sources to that information.
The frictional force is directly proportional to the force that is perpendicular on the surface.
When the body is placed on a horizontal level with zero inclination, the only force acting on the body is the gravitational force which always pulls the body down. The gravitational force, in this case, is the perpendicular force to the surface. Accordingly, this entire force is used to generate friction
Now as the inclination of the surface increases, the gravitational force is no longer the perpendicular force of the body, its value decreases, which means only a part is used to generate frictional force. Consequently, frictional force decreases.
When the inclination reaches 90 degrees, the gravitational force does not act along the normal and accordingly, no friction force is generated.
1.
Answer:
Part a)
Part b)
Explanation:
Part a)
Length of the rod is 1.60 m
diameter = 0.550 cm
now if the current in the ammeter is given as
V = 17.0 volts
now we will have
R = 0.91 ohm
now we know that
Part b)
Now at higher temperature we have
R = 0.98 ohm
now we know that
so we will have
2.
Answer:
Part a)
Part b)
Explanation:
Part a)
As we know that current density is defined as
now we have
Now we have
so we will have
Part b)
now we have
so we have
so we have
Hydroelectric power. That's just the term for electricity gained by using water, think of a water mill.
