Answer:

The dimension formula of X is T and that of Y is  T^2

Explanation:

                     d = aX + bY is ACTAULLY  [tex]S = V_{i} t + \frac{1}{2} a t^{2}[/tex]

                     so v = LT^-1

                          t = T

                          numerics do not have any dimensional formula so ignore [tex]\frac{1}{2}[/tex]

                          a = LT^-2

                          t = T^2

                         So answer for x is T and y T^2

Answer:

Balance scale would be the answer

Answer:

The basic SI unit of mass is the kilogram (kg). In physics, mass is not the same as weight, even though mass is often determined by measuring the object's weight using a spring scale, rather than balance scale comparing it directly with known masses.

Proton therapy, also called proton beam therapy, is a type of radiation therapy. It uses protons rather than x-rays to treat cancer. A proton is a positively charged particle. At high energy, protons can destroy cancer cells.

Answer:

4x10=30

Explanation:

You can easily know it's multiplication when you see the sign. It gives you the number but you have to plug it in. So once you plug in the numbers then you should get either 4x10 or 10x4 which means both is equal to 40

Explanation:

As we all know,mass is the amount of substance a body contains. So because Ice's mass is less than water, that's why it's able to float. In other words,we say ice is less dense than water

A volume of ice has less mass than the same volume of water. Hence, ice floats in water. Option (C) is correct.

The density of a material indicates the density of that material in a specific area. The density of a material is defined as its mass per unit volume. Density is a measurement of how closely matter is packed together. It is a distinct physical property of a specific object.

Archimedes, a Greek scientist, discovered the density principle. If you know the formula and understand the units, calculating density is simple. Density is represented by the symbol ρ, which can also be represented by the letter D.

Now, ice has less density compare to water. So, a certain volume of ice has less mass than the same volume of water. Hence, option(C) is correct.

Explanation:

v=(6)+(3)(15)

v=51m/s^1

Answer:

No; the graph fails the vertical line test.

The vertical line test is a tool used to determine if we have a function. If we can draw a single straight vertical line through more than one point on the red curve, then the graph is said to have failed the vertical line test. Consequently, this leads to the relation not being a function.

For this circle graph, we can draw a vertical line through more than one point, which is why we don't have a function here.

Put another way, there are inputs (x) that produce more than one output (y), so that's why we don't have a function.

v = ∆s / ∆t

v =?

∆s = 236 - 218 = 18km

Answer:

m2 = 13950 [kg]

Explanation:

To solve this problem we must use the principle of conservation of linear momentum, which is defined as the product of mass by velocity, and can be determined by means of the following expression:

P = m*v

where:

P = lineal momentum [kg*m/s]

m = mass [kg]

v = velocity [m/s]

Now that momentum is conserved, we need to analyze the conditions before the collision and after the collision. In this way we must propose the following equation:

ΣPbefore = ΣPafter

(m1*v1) + (m2*v2) = (m1+m2)*v3

where:

m1 = mass of the railroad car = 9300 [kg]

v1 = velocity of the railroad car before the collision = 15 [m/s]

m2 = mass of the box car [kg]

v2 = velocity of the boxcar before the collision = 0 (the car is at rest)

(m1 + m2) = combined mass of the cars, they stick together after the collision [kg]

v3 = combined velocity of the cars after the collision = 6 [m/s]

(9300*15) + (m2*0) = (m1+m2)*6

139500 = (6*9300) + 6*m2

83700 = 6*m2

m2 = 13950 [kg]

The mass of the second railroad car which was initially at rest is 13950kg.

Given the data in the question;

Mass of railroad car2; [tex]m_2 = \ ?[/tex]

Since railroad car2 was initially at rest,

After the strike, the wo cars stick together and moved

To determine the mass of the second railroad car, we use conservation of linear momentum:

[tex]m_1u_1 + m_2u_2 = (m_1 + m_2 )v[/tex]

We substitute our given values into the equation

[tex](9300kg * 15m/s) + ( m_2 * 0 ) = ( 9300kg + m_2 )6m/s\\\\9300kg * 15m/s = ( 9300kg + m_2 )6m/s\\\\139500kg.m/s = 55800kg.m/s + ( m_2 * 6m/s )\\\\139500kg.m/s - 55800kg.m/s = m_2 * 6m/s\\\\83700kg.m/s = m_2 * 6m/s\\\\m_2 = \frac{83700kg.m/s}{6m/s} \\\\m_2 = 13950kg[/tex]

Therefore, the mass of the second railroad car which was initially at rest is 13950kg.

Explanation:

The Rock cycle is a model that describes the formation degradation, and regeneration of rocks as a result of sedimentation magma, and metamorphism. All rocks are made of minerals.

Rock circulation is the process by which rocks change continuously between three types igneous sedimentary and metamorphic. The three processes that transform one rock into another are crystallization, metamorphism erosion, and sedimentation. Any rock can be transformed into another rock by undergoing one or more of these processes. This creates a lock cycle.

Rock circulation is a fundamental concept that describes the transition between three rock types metamorphic igneous, and sedimentary rocks. Simply put it is a set of processes that create and transform rock types within the Earth's crust. Rock cycling by definition is the natural process by which sedimentary igneous, and metamorphic rocks are formed, transformed from one type to another, and destroyed.

when the power is positive, you just need to move decimal point to your right , for a number of times which is similar to the value of the power.

Eg. 3.47×10 raised to the power 8.

with this, move the decimal point to the right eight times which will be 347,000,000.

But when the power is negative, move the decimal point to the left for a number times which will be similar to the value of the power.

Eg. 1.96×10 raised to the power negative 3.

move the decimal point leftwards three times which will be 0.00196
