Answer: weightlifter D

Explanation: solution attached:

Work is the product of force and distance

W= F x d = mg x d

Substitute the values:

Weightlifter A

W = 100 kg x 9.8 m/s² x 2.25 m

= 2205 J

Weightlifter B

W = 150 kg x 9.8 m/s² x 1.76 m

= 2587.2 J

Weightlifter C

W = 200 kg x 9.8 m/s² x 1.50m

= 2940 J

Weightlifter D

W= 250 kg x 9.8 m/s² x 1.25 m

= 3062.5 J

So weightlifter D has the greatest amount of work

3. In what circumstance will a flash of lightning travel through the sky and touch the ground?

alexgriva [62]

Answer: The answer is both. Cloud-to-ground lightning comes from the sky down, but the part you see comes from the ground up. A typical cloud-to-ground flash lowers a path of negative electricity (that we cannot see) towards the ground in a series of spurts.

Scorpion4ik [409]

Imagine you were able to throw a ball in a frictionless environment
such as outer space. Once you let go of the ball, it will travel forever
in a straight line, and at a constant speed. (At least until it bumps into
something.)

A car accelerates down the road. The reaction to the tires pushing
on the road is the road pushing on the tires.

Find the work done in pumping gasoline that weighs 6600 newtons per cubic meter. A cylindrical gasoline tank 3 meters in diamete

almond37 [142]

Answer:

work done in pumping the entire fuel is 1399761 J

Explanation:

weight per volume of the gasoline = 6600 N/m^3

diameter of the tank = 3 m

length of the tank = 6 m

The height of the tractor tank above the top of the tank = 5 m

The total volume of the fuel is gotten below

we know that the tank is cylindrical.

we assume that the fuel completely fills the tank.

therefore, the volume of a cylinder =

where r = radius = diameter ÷ 2 = 3/2 = 1.5 m

volume of the cylinder = 3.142 x x 6 = 42.417 m^3

we then proceed to find the total weight of the fuel in Newton

total weight = (weight per volume) x volume

total weight = 6600 x 42.417 = 279952.2 N

therefore,

the work done to pump the fuel through to the 5 m height = (total weight of the fuel) x (height through which the fuel is pumped)

work done in pumping = 279952.2 x 5 = 1399761 J

Definition of angle of incidence

Nadusha1986 [10]

The definition of incidence is In geometric optics, the angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal.
