Answer:
becuz of less friction of glass and more friction of rubber
Answer:
(a). The rotational inertia is
(b). The magnitude of the magnetic torque is
Explanation:
Given that,
Mass of neutron
Density of neutron
(a). We need to calculate the rotational inertia
Using formula of rotational inertia for sphere
...(I)
We know that,
Put the value of volume
Put the value of R in equation (I)
Put the value into the formula
The rotational inertia is .
(b). We need to calculate the magnitude of the magnetic torque
Using formula of torque
Put the value into the formula
The magnitude of the magnetic torque is
Hence, (a). The rotational inertia is
(b). The magnitude of the magnetic torque is
The angle that the cart rolls with the horizontal. The closer the ramp gets to 90 degrees the faster the cart will accelerate.
Answer: Explanation:
A number used to multiply a variable. Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient. ... Example: In ax^2 + bx + c, "x" is a variable, and "a" and "b" are coefficients.
We only need to look at Newton's 2nd law of motion:
Net force = (mass) x (acceleration)
If the net force on an object is zero, then either its mass or its acceleration must be zero. If it's called an "object", then its mass isn't zero, so its acceleration is zero.
