The potential difference of a current of 0.2A that flows through a component with a resistance of 40 ohms is 8V.

Potential difference is difference in potential energy between two points in an electric field i.e. the difference in charge between two points in an electrical circuit.

The potential difference of an electrical current can be calculated by multiplying the current by the resistance as follows:

Voltage = current (I) × resistance (R)

According to this question, a current of 0.2A flows through a component with a resistance of 40 ohms. The potential difference is as follows:

V = 0.2A × 40ohms

V = 8V

Therefore, the potential difference of a current of 0.2A that flows through a component with a resistance of 40 ohms is 8V.

The area swept by the wiper blade is 1324.04 inches^2.

The top and bottom ends of a windshield wiper blade move in the form of a circle.

The area swept by the wiper blade can be calculated by subtracting the area covered by the bottom end by the area covered by the top end i.e,

Area swept by blade(A) = Area covered by top end of blade - Area covered by bottom end of blade

A = A1 - A2

A1 =  π(13)^2 x 165/360 = 1567.25 inches^2

A2 = π(33)^2 x 165/360 = 243.21 inches^2

A= 1567.25 - 243.21 = 1324.04 inches^2

An open parachute expands the skydiver’s cross-sectional area as he falls, increasing the amount of air resistance he faces (as observed in the animation below).

As soon as the parachute is opened, air resistance outweighs the pull of gravity.

According to the drag equation, drag D is equal to the drag coefficient. Cd multiplied by density r, velocity V squared, and the reference area.

We must choose a value for Cd in order to calculate drag given the air conditions, shape, and inclination of the object.

Answer:

It's C

Explanation:

The reason why is since AM is longer as shown in the diagram it's either A or C, and since longer wavelengths have less energy it's C.

Additional heat will boost the temperature of the liquid once all of the solid has melted.

It is possible to recognize pure compounds and elements by their distinctive melting temperature, which is a characteristic number.

Energy is solely directed at changing a substance’s phase during melting; it is not used to alter the substance’s temperature.

Because a substance maintains the same temperature during melting, it is an isothermal process.

Even when any kind of heat is applied, the substance’s temperature remains properly constant during melting and boiling.

When the block is 5.00 m from the incline's summit, its velocity is 3.04 m/s.

provided details:

s = 7.80 m

v = 3.8 m/s

if s = 5 m, v?

The block's acceleration must first be determined using the following equation:

Since v02 = 0 due to v2 = v02 + 2as,

3.8² = 2 a 7.8

a = 0.93

Consequently, the final speed is if s = 5m.

The static frictional force acting on the block is equal to 90 Newton's.

Friction is a force that acts opposite to the direction of motion of body in order to oppose its motion. Frictional force is of two types -

The Static frictional Force - F[s] = μ[s] N

The Kinetic frictional force - F[k] = μ[k] N

Given in the question is a box of weight 120 N initially resting on a horizontal table. From the data given, we can write -

Weight of box [W] = 120 Newton

Coefficient of static friction (μ[s]) = 0.75

Coefficient of Kinetic friction (μ[k]) = 0.40

Horizontal push (F[h]) = 84 N

We know that -

F[s] = μ[s] N           [Static friction]

F[k] = μ[k] N           [Kinetic friction]

Now, initially the box is at rest so the opposite frictional force will be 0.  When a horizontal force of 84 Newton is applied on it, the static friction will try to oppose the motion. For forward motion of the block -

F[h] = F[s]

F[h] = μ[s]

84 = 0.75 x 120            (Normal Reaction [N]  = Weight)

84 = 90 ≥ 0

- 6 = 0

which is false.

This means that the static frictional force is greater than horizontal push and opposes the motion. The force due to static friction will only exist since, the body was able to move, so kinetic friction is of no use here.

So, the frictional force on the block will be = F[s] =  μ[s] N = 90 Newtons.

Therefore, the static frictional force acting on the block is equal to 90 Newton's.
