A box has a mass of 6.0 kg. What is its weight on the mars, where the acceleration due to
gravity is 0.38 times that on Earth? *

Answers

Answer 1

Answer:

The weight of the box is 22.38 N.

Explanation:

The weight (W) of the mass is given by:

[tex] W = mg [/tex]

Where:            

m: is the mass of the box = 6.0 kg

[tex]g_{m}[/tex]: is the acceleration due to gravity of mars

Since the acceleration due to the gravity of mars is 0.38 times that on Earth we have:

[tex]g_{m} = 0.38g_{E} = 0.38*9.81 m/s^{2} = 3.73 m/s^{2} [/tex]

Hence, the weight of the mass is:

[tex] W = mg = 6.0 kg*3.73 m/s^{2} = 22.38 N [/tex]

Therefore, the weight of the box is 22.38 N.

I hope it helps you!

D) The particle is the wave (wave packet)

Answers

Explanation:

In a longitudinal wave the particle displacement is parallel to the direction of wave propagation. The particles do not move down the tube with the wave; they simply oscillate back and forth about their individual equilibrium positions. Pick a single particle and watch its motion.

D. A small amount of the mass in each nucleus that undergoes a

reaction is converted to energy.

Two statements, that describe what happens in both nuclear fusion and nuclear fission reactions, are:

Radiation is released from the nuclei that undergo a reaction.A small amount of the mass in each nucleus that undergoes a reaction is converted to energy.

Hence, option (C) and (D) are correct.

What is nuclear reaction?

A nuclear reaction is a process in nuclear physics and nuclear chemistry where two nuclei or a nucleus and an outside subatomic particle meet to create one or more new nuclides. Consequently, at least one nuclide must change throughout a nuclear reaction.

Instead of being referred to as a nuclear reaction, the process is simply referred to as a sort of nuclear scattering if a nucleus interacts with another nucleus or particle and they subsequently separate without altering the nature of any nuclide.

A piece of wire length 30cm and cross sectional area of 0.5mm^2 has a resistance of 5ohms at 20°c. It is then heated to a temperature of 150°c. Calculate it's resistivity at 20°c

Answers

Answer:

8.333*10^-6 ohms

Explanation:

Resistivity of a material is expressed as;

p = RA/l

R is the resistance of the material

A is the cross sectional area

l is the length of the material

Given

R = 5 ohms

A = 0.5mm^2

A = 5 * 10^-7m^2

l = 30cm  = 0.3m

Substitute into the formula;

p = (5 *  5 * 10^-7m^2)/0.3

p = 25 * 10^-7/0.3

p = 0.0000025/0.3

p = 8.333*10^-6

Hence its resistivity at 20 degrees Celsius is 8.333*10^-6 ohms

Complete question:

A 0.144 kg baseball approaches a batter with a speed of 20m/s . The batter lines the ball directly back to the pitcher with a speed of 30m/s . Find the impulse exerted on the ball . If the bat and ball were in contact for 0.012 sec , find the average force exerted on the ball by the bat

Answer:

(1) The impulse exerted by the ball is 7.2 kg.m/s

(2) The average force exerted on the ball by the bat is 600 N.

Explanation:

Given;

mass of the baseball, m = 0.144 kg

velocity of the baseball, v₁ = 20 m/s

velocity of the batter, v₂ = -30 m/s (opposite direction to the ball's speed)

The impulse exerted by the ball is calculated as follows;

J = ΔP = mv₁ - mv₂

ΔP = m(v₁ - v₂)

ΔP = 0.144 [20 - (-30)]

ΔP = 0.144 ( 20 + 30 )

ΔP = 0.144 (50)

ΔP = 7.2 kg.m/s

The average force exerted on the ball by the bat is calculated as;

[tex]F = \frac{\Delta P }{t} \\\\where; t \ is \ time \ of \ contact= 0.012 \ s\\\\F = \frac{7.2}{0.012} \\\\F = 600 \ N[/tex]

Burning fuel in a rocket causes a push that propels the rocket forward from the front. The exhaust gas is pushed rearward in an equal and opposite direction as a result.

What is Newton’s law?

The three fundamental laws of classical mechanics known as Newton's laws of motion describe how an object's motion and the forces acting on it interact.

The following is a paraphrasing of these laws: Unless a force acts upon a body, it remains at rest or in continual straight-line motion.

The creation of thrust by a rocket engine can be understood via Newton's third law. In a rocket engine, a fuel and an oxidizer are burned to produce hot exhaust gas.

The hot exhaust gas from the rocket accelerates to the back of the rocket after passing through the nozzle.

Thus, this way, Newton’s law of action–reaction best be applied to rocket movement.

Train A leaves the station heading north at 80 mph. At the same time and from the same station, Train B heads south 65 mph. How far apart are the trains after 3 hours fo travel?

Answers

Answer:

The trains will be 435 miles apart

Explanation:

Distance covered by the two trains can be obtained by multiplying their speeds with the time frame under consideration - in this our case, it is  3hours.

For Train A

Distance covered = 80mph X 3 hours = 240miles

For train B

Distance covered = 65mph X 3 hours = 195 miles.

The total distance between the two trains after 3 hours will be

240 + 195 = 435 miles

The spring constant of the given bow spring is equal to  1.77 × 10⁵ N/m.

What is Hooke's law?

Hooke's law can be described as a law that states that the force (F) required to extend or compress a spring by displacement linearly with respect to that displacement along a straight line.

The spring force can be represented in the form of an equation:

F = -kx

where k is a spring constant of the spring and x is the deformation of the spring. The negative sign shows that force is restoring force.

The energy that can be stored in the spring when it is stretched is given by:

E = (1/2)kx²

Given, the energy stored in the spring when it is stretched, E = 1000J

The distance by which the bow spring is stretched, x = 0.15 m

2000 =  (1/2) × k (0.15)²

k = 1.77 × 10⁵ N/m

Answer:

Option C. 83.8 J

Explanation:

From the question given above, the following data were obtained:

Mass (m) of object = 2 Kg

Velocity (v) of the object = 5 m/s

Height (h) = 3 m

Mechanical energy =.?

Next, we shall determine the kinetic energy of the object. This can be obtained as shown below:

Mass (m) of object = 2 Kg

Velocity (v) of the object = 5 m/s

Kinetic energy (KE) =?

KE = ½mv²

KE = ½ × 2 × 5²

KE = 1 × 25

KE = 25 J

Next, we shall determine the potential energy of the object. This can be obtained as shown below:

Mass (m) of object = 2 Kg

Height (h) = 3 m

Acceleration due to gravity (g) = 9.8 m/s²

Potential energy (PE) =.?

PE = mgh

PE = 2 × 9.8 × 3

PE = 58.8 J

Finally, we shall determine the mechanical energy of the object. This can be obtained as shown below:

Kinetic energy (KE) = 25 J

Potential energy (PE) = 58.8 J

Mechanical energy =?

Mechanical energy = KE + PE

Mechanical energy = 25 + 58.8

Mechanical energy = 83.8 J
