A torque applied to a flywheel causes it to accelerate uniformly from a speed of 161 rev/min to a speed of 853 rev/min in 5.0 se

The new gravitational force would be calculated as follows: Consider the general formula for the gravitational force between two masses m1 and m2 that are separated by a distance "d". For the two trucks weighing 2,000 kg each, the gravitational force is initially 3.00 × 10-5 N. When one truck is loaded with an additional 1,000 kg of bricks, we need to determine the new gravitational force (x). We find this by dividing the last equation by the original to eliminate common factors (G, d^2).

Answer:

The accurate equations are T-fg=ma and L-fg=0.

Options (A) and (C) are valid.

Explanation:

Given that:

Weight Fg = mg

Acceleration = a

Tension = T

Drag force = Fa

Vertical force = L

We are required to determine the correct relationships

Using the equilibrium equations

Horizontally,

The acceleration is a

...(I)

Vertically,

No acceleration occurs

Substituting the value of mg

....(II)

Thus, the correct relationships are T-fg=ma and L-fg=0.

Options (A) and (C) are correct.

Answer:

267.07 km

Explanation:

The given earth's radius is 6378.1 km

In the year 2014, the magnetic north pole was situated 2.40° away from the geographical north pole

2.40°

The linear distance can be calculated using the formula

Thus, travelling from the magnetic north pole to the geographic north pole requires a distance of 267.07 km

When helium is released from a compressed container, the decompressed atoms expand and rise, causing the rubber balloon to inflate and float along. In this scenario, helium exists in a gaseous state.
