When the engine is near the governed RPMand the transmission is in the lower gears, the braking effect of the engine is at its greatest .
It is specified that the legal requirements for the braking system that:
A reasonable distance should be practiced in stopping your vehicle.
Adjournment from the jar or shudder should be smooth and free.
A good braking system’s other necessities are:
Unaffected by heat, water, road grit, dust etc.
Constant continued application while moving downwards from a hill should not decrease its effectiveness and it must have good anti fade characteristics
Adequate durability with economical maintenance and adjustment Its durability must be enough and must have proper adjustment and maintenance.
Answer:
20 miles
Explanation:
Use pythagorean theorem
d^2 = 16^2 + 12^2
to find displacement, d = 20 miles
Answer:
c Like/same signs
Explanation:
A repelling force occurs between two or more charged objects with the charges are of like or same sign.
- According to Coulombs law, like charges repel on another, unlike charges attracts on another.
- If a positive charge comes into the vicinity of another positive charge, there will be repulsion.
- When oppositely charge species are brought near each other, there is an attraction.
Therefore, repulsion occurs when like charges are brought close to each other.
Answer:
it will be zero degree
the angle of reflection is zero on hemisphere sides and angle of i is equal to angle of r
Answer:
Normal force will be equal to 8.945 N
Explanation:
We have given mass of the cylinder m = 8.15 kg
Diameter d = 15 cm
So radius
Initial angular velocity
As the cylinder finally comes to rest so final angular velocity
Before coming to rest cylinder covers a distance of
From third equation of motion
Coefficient of kinetic friction
Moment of inertia of the solid cylinder
We know that
So normal force will be equal to
