Explanation

Both bullets will hit the ground simultaneously.

The horizontal speed and mass do not affect the time to fall; only gravity influences vertical motion.

Since they are fired from the same height, they will experience the same vertical acceleration and hit the ground at the same time.

Explanation

If the conductor carrying current experiences a magnetic force at an angle of 90 degrees, and then the angle decreases to 60 degrees, the force will decrease because the component of the magnetic field perpendicular to the current-carrying conductor decreases as the angle decreases.

Explanation

“Elaborate with examples, the first law of motion” indicates comprehension.

Explanation

Explanation

Two waves of unequal amplitude do not cause stationary waves.

Stationary waves are formed when two waves of equal amplitude, frequency, and speed travel in opposite directions and interfere with each other.

Explanation

The incorrect statement is "Distance between consecutive nodes is 1 wavelength."

The distance between consecutive nodes is actually 1/2 wavelength, as nodes are points of no displacement in standing waves.

It occurring at intervals of half the wavelength along the string.

Explanation

The expression (1-v^2/c^2)^-0.25 is always greater than one because it represents the Lorentz factor, which accounts for time dilation and length contraction in special relativity.

Explanation

• Charge: Q=1mC=1×10^−3C

• Voltage: $V = 100,text{V}$

• The formula for capacitance is:

C=Q/V​

Calculation:

$$C = frac{1 times 10^{-3}}{100} = 1 times 10^{-5},text{F} = 10,mutext{F}$$
