Answer:
5. independent of its amplitude.
3. inversely proportional to its acceleration
Explanation:
The time period of oscillation is mathematically given as:
where:
length of the string through which the body oscillates.
acceleration due to gravity.
So, we can observe that it is independent of amplitude and depends on acceleration due to gravity and the length of the oscillating string.
Answer:
The total electric flux through the shell = 34804 N.m²/C
Explanation:
φ = E.A ........................... Equation 1
Where φ = total electric flux through the shell, E = Electric Field, A = surface Area of the sphere
But,
A = 4πr² ................................... Equation 2
Where r = radius of the sphere.
Given: r = 1.4 m,
constant: π = 3.143
Substituting these values into equation 2,
A = 3.143(1.4)²
A = 6.16 m²
Also Given: E = 5650 N/C,
Substituting into equation 1,
φ = 5650(6.16)
φ = 34804 N.m²/C
Thus the total electric flux through the shell = 34804 N.m²/C
Answer:
Even in space, objects have mass. And if they have mass, they have inertia. That is, an object in space resists changes in its state of motion. A force must be applied to set a stationary object in motion.
Answer:
11.25km/h²
Explanation:
Acceleration = Velocity / Time
Acceleration = 90 / 8
Acceleration = 11.25
