Consider a 2 m wide and 5 m long slab resting on flat, fixed, earthen bed. The slab is 20 cm thick with uniform properties. You

may assume the slab is much longer and wider than it is thick. Write the reduced form of the governing equation for the slab. Clearly identify your coordinate system on a sketch and state your assumptions identifying which terms you are eliminating and why.

Answer:

Explanation:

The coordinate sketch for the system is shown in the attached file below. Also, in the cartesian coordinate system, since the height is less than the length and width, we did neglect the height. Thus, we eliminate the height and converted it to a two-dimension.

The electrostatic force between two charges located 2 meters apart is 0.10 N. What will the force be between these charges when
Vikentia [17]
Given that 2 m is to .10N

we will set up a ratio & proportion

.10 x
— —
2 1

cross multiply

2x = .10(1)

divide both sides by 2

x (and the answer) = .05 N

Suppose our experimenter repeats his experiment on a planet more massive than Earth, where the acceleration due to gravity is g
Ne4ueva [31]

Answer:

C

Explanation:

- Let acceleration due to gravity @ massive planet be a = 30 m/s^2

- Let acceleration due to gravity @ earth be g = 30 m/s^2

Solution:

- The average time taken for the ball to cover a distance h from chin to ground with acceleration a on massive planet is:

                                 t = v / a

                                 t = v / 30

- The average time taken for the ball to cover a distance h from chin to ground with acceleration g on earth is:

                                 t = v / g

                                 t = v / 9.81

- Hence, we can see the average time taken by the ball on massive planet is less than that on earth to reach back to its initial position. Hence, option C

What is the equivalent resistance of the circuit?
Ivanshal [37]

Answer:

Since the wire is not splitting at any point in the circuit,

the resistors are in series

Hence, Equivalent resistance = 10 + 20 + 30

Equivalent Resistance = 60 Ω

A dog walks along The ground. If the dog applies an action force on the ground, what is the reaction force?
fiasKO [112]

Explanation:

Action and reaction are two forces that are equal in magnitude but the direction is opposite.

When a dog walks along the ground, the action force is the force that dog applies on the ground. On the other hand, the reaction force is the force that the ground applies on the dog. It is based on Newton's third law of motion.
