A box is at rest on a slope with an angle of 40.0o to the horizontal. If the mass of the box is 10.0kg, what is the perpendicular component of the weight?63.0N6.43N7.66N75.1N

Answers

Answer 1

The perpendicular component of the weight is approximately 75.1 N.



The perpendicular component of the weight is equal to the weight of the box multiplied by the cosine of the angle between the weight vector and the perpendicular direction. In this case, the weight vector is pointing straight down, and the angle between it and the perpendicular direction is equal to the angle of the slope, which is 40.0 degrees.


where weight = mass * gravity, and gravity is the acceleration due to gravity, which is approximately 9.81 m/s^2.
weight = 10.0 kg * 9.81 m/s^2 = 98.1 N
cos(40.0) = 0.7660
perpendicular weight = 98.1 N * 0.7660 = 75.1 N
Therefore, the perpendicular component of the weight is 75.1N.

An 12 kg object accelerating from 9 m/s to 14 m/s. What is the change in momentum of the object?

Answers

Answer:

Change in momentum = 60kgm/s.

Explanation:

Given the following data;

Mass, m = 12kg

Initial velocity, u = 9m/s

Final velocity, v = 14m/s

Momentum can be defined as the multiplication (product) of the mass possessed by an object and its velocity. Momentum is considered to be a vector quantity because it has both magnitude and direction.

Mathematically, momentum is given by the formula;

[tex] Momentum = mass * velocity [/tex]

To find the change in momentum;

Mathematically, change in momentum is given by the formula

[tex] Change \; in \; momentum = m(v - u) [/tex]

Substituting into the equation, we have;

[tex] Change \; in \; momentum = 12(14 - 9) [/tex]

[tex] Change \; in \; momentum = 12*5[/tex]

Change in momentum = 60kgm/s.

Scientific study simply means establishing the existence or proving the veracity of an hypothesis, hence making it a fact. A scientific study follows an orders set of procedure;

Asking a question is the first step as this is what prompts the research, question usually stems after making an observation.

The a observation made and question asked will lead to making research on the observed phenomenon, this is to check if such question has been asked in the past and maybe any scientific study as been carried out in the past.

To make research further, an hypothesis is defined in a bid to find more evidence to support one's observation through experiment.

Study design and implementation is next as the type of study to be embarked upon will determine which type of design preparation and study pattern to deploy.

Conclusion a d report of observations made are the last part of a scientific study which is key as all outcomes of the study should be adequately detailed in an understandable format while also ensuring reproducibility.

What is the moon phase?

The moon changes shape every day. This is due to the fact that the celestial body has no light of its own and can only reflect sunlight.

Only the side of the moon facing the sun can reflect this light and seem bright. On the opposite side appears black is a full moon.

We can only see the black section when it lies between the sun and the earth when a new moon occurs. We witness intermediate phases like a half-moon and crescent in between these two extremes.

The moon changes shape every day the changes in their shape are defined as the moon phase.

In general, we may estimate the third by knowing any two of the following three things

(1) the moon's position in the sky

(2) the moon phase

(3) the time

Hence in positions 1 and 5 first-quarter moon and last quarter moon appear to an observer on Earth.

What is an Environment?

All living or non-living objects that occur naturally, or in this example, without the use of artificial means, are included in the natural surroundings or natural world. The phrase is most frequently used with reference to Earth or certain regions of it.

An environment encompasses all that surrounds us, including both living and dead objects like water, soil, plants, and animals that can adapt to their environment. The gift of nature is what sustains life on Earth.

Environment can be summed up as the effects of every one of the living or non-living things that have an impact on human life. Non-living or abiotic elements include water, land, sunshine, rocks, and air, whereas all live or biotic components are animals, plants, forests, fisheries, and birds.

A bus negotiates a curve of radius 487 m. What force will be exerted on an 80 kg passenger by the outside wall of the bus when it is traveling at 60 km/h?

Answers

Answer:

Centrifugal Force = 45.65N

Explanation:

Given the following data;

Mass, m = 80kg

Radius = 487m

Velocity = 60km/h to m/s = 60*1000/3600 = 16.67m/s

To find the centrifugal force;

Centrifugal Force = mv²/r

Substituting into the equation, we have;

Centrifugal Force = 80*16.67²/487

Centrifugal Force = 80*277.89/487

Centrifugal Force = 2223.12/487

Centrifugal Force = 45.65N

Alli was in the park playing on the equipment. She noticed that on the highest slide, she slides down with the greatest speed. The correct option is C.

What is the relation between height and speed?

Height is the measurement of someone or something from head to foot or from base to top.

The curved slide is the fastest, despite being longer than the other circuits. This is due to the fact that it is steeper at first, leading the ball to be more affected by gravity and accelerate more quickly before reaching its top speed.

When two items rub against one another, as a slide and a person's bottom, friction is created. A slide would accelerate the rider too quickly without friction, possibly injuring them. Various substances known as lubricants can lessen the impact of friction.

Therefore, the correct option is C) With the greatest speed.
