I think the correct answer from the choices listed above is option B. If asked to describe a wave, you could say waves are the continuous transmission of energy from one location to the next. <span>In physics, a </span>wave<span> is an oscillation accompanied by a transfer of energy that travels through a medium. Hope this helps.</span>

A sprinter accelerates from rest to 10.0m/s in 1.35s.

ANEK [815]

Answer:

a) Acceleration = 7.41 m/s^2

b) Distance ran = 6.75 m

Explanation:

For Acceleration use the formula...

a = (v - u) ÷ t....where v=10 and u=0....and t=1.35

a = (10 - 0)÷ 1.35

;acceleration = 7.41m/s^2

For the distance moved in 1.35s

;use the...s = ut + 1/2at^2....where s is the distance moved

;s = (0)(1.35) + 0.5(7.41 × 1.35^2)

Distance moved = 6.75m

Step 2 does the robotic arm do work on the block. Joshua programs a robotic arm to place a block in a box. a four-row, two-column table.

<h3>What is a robotic arm?</h3>

A robotic arm is a type of artificial arm that may be programmed to do tasks similar to those of a human arm.

The arm can be the sum of the mechanism or part of a larger robot. Joints connect the manipulator's linkages, allowing rotational or translational motion.

By following the directions in the table, Joshua programs a robotic arm to place a block in a box. a four-row, two-column table.

The items in the first column labeled step are 1, 2, 3, and 4. Grip block, elevate block 10 cm, hold for 20 seconds, release block are the items in the second column labeled command.

Step 2 does the robotic arm do work on the block.

Hence,step 2 is the correct answer.

Now suppose that the Earth had the same mass and radius as it currently does, but all of the mass was concentrated into a thin (

KiRa [710]

Answer:

The force of gravity at the shell will be extremely great on me due to the huge mass collapsed into the small radius.

<em>At the center of the shell, the gravitational forces all around should cancel out, giving me a feeling of weightlessness; which will be a lesser force compared to that felt while standing on the shell.</em>

Explanation:

For the collapsed earth:

mass = 5.972 × 10^24 kg

radius = 1 ft

according to Newton's gravitation law, the force of gravity due to two body with mass is given as

Fg = GMm/ $R^{2}$

Where Fg is the gravitational force between the two bodies.

G is the gravitational constant

M is the mass of the earth

m is my own mass

R is the distance between me and the center of the earths in each case

For the case where I stand on the shell:

radius R will be 1 ft

Fg = GMm/ $1^{2}$

Fg = GMm

For the case where I stand stand inside the shell, lets say I'm positioned at the center of the shell. The force of gravity due to my mass will be balanced out by all other masses around due to the shell of the hollow earth. This cancelling will produce a weightless feeling on me.

How is volume calculator giving mass and density

ohaa [14]

Divide the mass by the density of the substance to determine the volume (mass/density = volume). Remember to keep the units of measure consistent. For example, if the density is given in grams per cubic centimeter, then measure the mass in grams and give the volume in cubic centimeters.
