Answer:

The pressure of the box on the floor is 200 Pa

Explanation:

Given,

Length of the box=0.5m

Width of the box= 0.1m

∴Area of the box, A= (0.5 X 0.1) sq.m

                                = 0.05 sq.m

We know,

Pressure, P= F/A

                  = 10/0.05 Pa

                  = 200 Pa

∴The pressure of the box on the floor is 200 Pa

When the forces on the object are unbalanced, the object will move in the direction of the greater force.

Newton's first law of motion states that an object at rest or uniform motion in a straight line will continue in that path unless acted upon by an external force and the object will tend to move in the direction of the applied force.

Newton's second law of motion states that the force applied to a body is directly proportional to the acceleration of the body.

F = ma

If the net force acting on a body is greater than zero, the body will tend to move in the direction of the greater force.

Thus, when the forces on the object are unbalanced, the object will move in the direction of the greater force.

Answer:

1.0147 rounded to the nearest thousandths place is 1.015

Answer:

1.015

Explanation:

If you put the number in place value, you have 1 in the ones place, 0 in the tenths place, 1 in the hundreds place, 4 in the thousandths place, and 7 in the ten thousandths place. In order to know how to round 4, you must look at the number directly after it. Since 7 is greater than five, round up to ten. This increases 4 by 1 which would give you the answer 1.015.

Answer:

279 m/s

Explanation:

Answer:

2m/s^2

Explanation:

A=(u-v)/t

where u=final velocity and v=initial velocity and t=time

therefore u =70 and v=0 because the question said velocity of rest and finally t=35

so, (70-0)/35= 70/35=2

Answer:

The saddle joint allows movement in different directions but only a small amount of rotation. The thumb is the only organ that has a saddle joint.

It should be noted that the bones that are in the saddle joint ensure the back and forth movement of the thumbs.

The pivot joint is the joint that's responsible for ensuring that one bone rotates around another bone. Ball and socket joint can be found in the shoulder and the hip and it allows for greater freedom of movement.

When compared to other movable joints, the saddle joint is prone to dislocation because it's free-moving and rotates on its own axis alone.

In conclusion, if the thumb contained a pivot joint or a ball and socket joint, it'll be able to move more freely.

Answer: A. Pure Substance

Explanation:

If it is pure the substance has to be either an element or a compound.

Answer:

A. pure substance

Explanation:

This is because matter has distinct properties and the ingredients from sample to sample do not change, and all substances are either elements or compounds

W = F × s

W = 15kN × 40 m

W = 15.000 N × 40 m

W = 600.000 J

P = W/t

P = 600.000 J/2 s

P = 300.000 Watt

Answer:

Baking a cake requires heat to be applied to the batter in order for it to cook and chemically change into cake. The energy or heat applied is absorbed by the ingredients, so this represents an endothermic reaction.

Explanation:

that's the sample answer, hope it helps

The batter needs to be heated in order to cook and chemically transform into a cake when it is baked. An endothermic reaction is taking place because the energy or heat applied is being absorbed by the constituents.

The quantitative characteristic that is transferred to a body or a physical system in physics is referred to as energy. It manifests itself as heat and light, as well as the act of doing work. Energy is a resource that is conserved; it can only be changed from one form to another and cannot be created or destroyed, according to the law of conservation of energy. The SI unit of energy measurement is the joule (J).

According to the question, there are various types of reactions two of which are endothermic reactions and exothermic reactions.

In an endothermic lot of energy is absorbed and in opposition to the exothermic reaction lot of energy is released.

I'm going to assume you mean

[tex]y = 14t^2 - \dfrac{t^2}{2+5t} - 3[/tex]

Taking the derivative with respect to t on both sides gives

[tex]\dfrac{\mathrm dy}{\mathrm dt} = 2\cdot14t - \dfrac{(2+5t)(2t)-t^2(5)}{(2+5t)^2} - 0 \\\\ \dfrac{\mathrm dy}{\mathrm dt} = \boxed{28t - \dfrac{4t+5t^2}{(2+5t)^2}}[/tex]

You could go on to expand the rational expression into partial fractions. One way to do this:

[tex]\dfrac{5t^2 + 4t}{(2 + 5t)^2} = \dfrac{t(5t+2) + 2t}{(2+5t)^2} \\\\= \dfrac{t}{2+5t} + \dfrac{2t}{(2+5t)^2} \\\\= \dfrac15 \cdot \dfrac{t}{\frac25+t} + \dfrac{2t}{(2+5t)^2} \\\\ = \dfrac15 \cdot \dfrac{t+\frac25-\frac25}{\frac25+t} + \dfrac{2t}{(2+5t)^2} \\\\ = \dfrac15 \left(1 - \dfrac{2}{2+5t}\right) + \dfrac{2t}{(2+5t)^2} \\\\ = \dfrac15 - \dfrac{2}{10+25t}+ \dfrac{2t}{(2+5t)^2}[/tex]

and this would give

[tex]\dfrac{\mathrm dy}{\mathrm dt} = 28t - \dfrac15 + \dfrac2{10+25t} - \dfrac{2t}{(2+5t)^2}[/tex]

that is also a rounded up decimal! to find your answer, divide the mass (13.8) by the density (6.2) to find your volume :)

Answer:

A.

Explanation:

In addition to helping you lose weight by using calories on more filling foods, following a low-fat diet can help you ward off serious medical conditions, including heart disease, high cholesterol, and diabetes. The body needs some fat to function properly.

If Yusef had a diet with absolutely no fat then He would have absolutely no energy. Hence A is correct option.

Fat aids in the body's absorption of vitamins A, D, and E. These vitamins are only absorbed with the aid of lipids because they are fat-soluble. Body fat is created from any fat that is not utilized by the body's cells or transformed into energy.

According to research, the majority of fat cells in adipose tissue are produced by cells that line the blood vessels. This realization might inspire fresh methods for treating and preventing obesity. Our metabolism, reproduction, and life lengths are all regulated by white adiposity, or fat, tissue.

Computers are widely used for modeling weather systems because because weather systems are too complicated to be accurately predicted using small-scale. Hence option A is correct.

Weather refers to the condition of the atmosphere and includes terms like how hot or cold, wet or dry, quiet or stormy, clear or foggy, etc. The troposphere, which is the lowest part of Earth's atmosphere and lies just below the stratosphere, is where most meteorological events take place. Climate is the phrase for the average of atmospheric conditions over longer periods of time, whereas weather is the term for day-to-day temperature, precipitation, and other atmospheric factors. Without more explanation, "weather" is typically taken to refer to the weather on Earth.

Differences in air pressure, temperature, and moisture from one location to another influence the weather. The Sun's angle at any given location, which changes with latitude, may be the cause of these variations.

Hence option A is correct.
