What is the acceleration of a 300. kg sled being pulled with a force of 828 N, if the coefficient of kinetic friction between the sled and the ground is 0.120?

We have that with v_1 =v this goes to show that  the velocity of the bigger block after the collision takes place is v

From the question we are told

Suppose the blocks collide elastically. picking the positive direction to the right, what is the velocity of the bigger block after the collision takes place?

Generally the equation for Momentum   is mathematically given as

P=mv

Therefore

[tex]m_1v_2=m_2v_2[/tex]

Hence

[tex]v_1=\frac{m_2v_2}{m_1}[/tex]

Therefore

[tex]v_1=\frac{mv_2}{2m}\\\\v_1=\frac{v_2}{2}[/tex]

Hence

[tex]2v+v=v_1+v_2\\\\v_1=v[/tex]

Now

with v_1 =v this goes to show that  the velocity of the bigger block after the collision takes place is v

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.

The slope of the graph, A, and the starting position of the ball, B, can be used to determine the position of the ball

Reason:

Question; The possible function representing the given equation is presented as follows;

x = A·t + B

Where;

A = 2.59 × 10⁴ [tex]\frac{cm}{s}[/tex]

B = 0.104 cm

t = Time in seconds (s)

x = The position (cm)

Required: The value of the position when t = 0.00231 s

Solution:

The position time graph of an object moving with a constant speed is a straight line with an equation of the form y = m·x + c

Plugging in the value of t = 0.00231 in the given equation gives;

x = 2.59 × 10⁴ × 0.00231 + 0.104 = 59.933

The position x of the ball at time, t = 0.00231 s is 59.933 cm

Answer: Given that:

Mass (m) = 20 g = 0.02 Kg,

temperature (T₁) = -10°C = -10+273 = 263 K

temperature (T₂) = 10°C = 10+273 = 283 K

Specific heat of water (Cp) = 4.187 KJ/Kg k

We know that Heat transfer (Q) = m. Cp.( T₂ - T₁)

                                                   = 0.02 × 4.187 × (283-263)

                                                Q = 1.67 KJ

Heat transferred is 1.67 KJ

Answer:

The object will have an acceleration and the object's velocity will change.

Explanation:

If there is a net force acting on an object, the object will have an acceleration and the object's velocity will change. Newton's second law states that for a particular force, the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object.

Measuring the volume of an irregularly shaped object using geometry is often difficult and complicated. The easiest way to do this is by using the water displacement method. Often taught in chemistry or other science classes, this method is known for its simplicity and accuracy.

Explanation:

Measuring the volume of an irregularly shaped object using geometry is often difficult and complicated. The easiest way to do this is by using the water displacement method.

Shortest distance between two point are called as displacement, or we can say that when a body moves between two points the total  lengths between two points are called as distance but the shortest distance between two point is called as displacement. Displacement is measured in meter and it is a vector quantity.  Displacement may became zero but distance never became zero.

In above problem we cam say that in a race car start form a point and reaches at the same point then it's displacement is zero because  there is no shortest distance. Displacement is measured in meter and it is a vector quantity.  Displacement may became zero but distance never became zero.

Therefore,Measuring the volume of an irregularly shaped object using geometry is often difficult and complicated. The easiest way to do this is by using the water displacement method.

Answer:

C

Explanation:

Newton's first Law of Motion is also known as law of inertia, which states that "an object at rest remains at rest, and an object that is moving will continue to move straight and with constant velocity, if and only if there is no net force acting on that object". As such, the correct option should be C.

Option A is Newton's third Law of Motion.

Option B is Newton's second Law of Motion

Option D is Newton's Law of Universal Gravity

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.

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.

Oxidation of certain metals in rock and acid rain breaking down compounds in rock statues are examples of chemical weathering.

When chemicals are diluted and dissolved in water, they seep and percolate down the surfaces of rocks, causing chemical weathering. Chemical weathering occurs in humid tropical regions and other places with high temperatures and a sufficient supply of water.

The reaction of chemicals in water or air causes minerals to change in composition as chemical weathering takes place. Additionally, this causes the breakdown of rocks. Leaching is the process of carrying away some components of rock breakdown through rocks and soil.

These materials may eventually be transported by the water to rivers and the sea. The oceans' saltiness comes from this source. Oxidation, the breakdown of calcium carbonate, and   acid rain breaking down compounds in rock statues by chemical reaction are examples of chemical weathering.
