The same force is applied to two skateboards. One rolls across the room and the other moves a few feet and comes to a stop. Wher

e was there more work done?
a. The skateboard that traveled the shorter distance shows more work because there was more resistance.
b. The skateboard that traveled the longer distance shows more work because it was lighter.
c. The skateboard that traveled further shows more work because the distance was greater.
d. The skateboard that traveled the shorter distance shows more work because the force was greater.

The question and all of the choices are rather messy and misleading.

Here's a simple statement that you can use to make the best match:

If the two forces are equal, then more work is done by the force that
continues to be applied through the greater distance.

Answer:

<h2>C</h2>

Explanation:

<h2>THIS IS TRUE BECAUSE I TOOK THE TEST, and because THE EQUATION FOR WORK IS WORK = FORCE * DISTANCE AND EVEN THO THEY BOTH HAVE THE SAME FORCE THE OTHER ONE HAS MORE DISTANCE, ITS LIKE SAYING WHICH EQUAION HAS A BIGGER ANSWER 1*1 OR 1*2 WELL ITS OBVIOUSLY THE SECOUND EQUATION SO THE ANSWER IS C LIKE I SAID BEFORE</h2><h2 /><h2>BTW  AL2006 IS WRONG AND I DONT EVEN UNDERSTAND WHAT HE EVEN THO HE IS "TRUSTED"</h2>

Goryan [66]

Answer:

Explanation:

one end of tank will be circular in shape . Area of circle A

= π r² , r is radius of the circle

= 3.14 x 3²

A = 28.26 ft³

To calculate force  on the circular area , we first find pressure at the center of the circle which is at depth equal to r

pressure at the center = h d g ' here h = depth = r   , d = density of milk

pressure = 3 x 64.6 x 32 poundal / ft²

= 6201.6 poundal / ft²

total force on circular face = pressure at the center x area of circle

= 6201.6 x 28.26

= 175257.21 poundal .

How many neutrons are needed to initiate the fission reaction shown?
nalin [4]

Answer: One neutron

Explanation:

one neutron 1/0n

Sum up the mass numbers on the right 99 + 135 + 2 = 236.

The sum of the mass numbers on the left should equal 236. 235 + 1 = 236

There is a plate with moment of inertia Ip = 0.0711 kgm2 , rotating around its center of mass with angular speed of 4.53 rad/s.
Anna007 [38]

Answer:

1) their common angular speed = 3.038 rad/s

2) kinetic energy loss = 0.24J

Explanation:

1) This is a case of conservation of angular momentum.

The initial angular momentum must be equal to the final angular momentum

Initial angular momentum = I x w

Where I = moment of inertia, and

w = angular momentum.

Initial angular momentum = 0.0711 x 4.53 = 0.322 kg-m2-rad/s

After addition of ring, moment of inertia becomes,

0.0711 + 0.0353 = 0.106 kg-m2

Therefore, final angular momentum will be

0.106 x Wf

Where Wf = final common angular velocity

Equating the two angular momentum we have

0.322 = 0.106Wf

Wf = 0.322/0.106 = 3.038 rad/s

2) KE = 1/2 x I x w^2

Initial KE = 1/2 x 0.0711 x 4.53^2

= 0.729 J

Final KE = 1/2 x 0.106 x 3.038^2

= 0.489 J

Loss in KE = 0.729 - 0.489 = 0.24 J

djyliett [7]

Answer:

B) The train is not an inertial frame of reference

C) The train may be instantaneously at rest

D) The train may be moving at a constant speed in a circle

H) The train must be accelerating.

Explanation:

Since the train is in constant motion, it is accelerating. The speed is varying with time. The train is not an inertial frame of reference since it is constantly moving.
