PLS HELP WITH THIS FOR BRAINLIST IF ITS RIGHT

 A pure substance cannot physically be separated, and is made out of one atom (or molecule). Unlike a mixture, however, which are made out of two or more atoms or molecules. A solution in itself is the example of a mixture. (The composition of a pure substance being fixed, and a mixture's being varying depending on which.) And a solution branching off from a mixture into being either homogeneous mixtures or heterogeneous mixtures.

srry it kinda turned into a paragraph lol, feel free to add or take away anything :)

Answer:

C.friction  

Explanation:

Answer: 9 Joules

Explanation:

Kinetic enegry is one half the mass multiplied by the velocity squared

KE = 1/2mv^2

[tex]KE=1/2(2)(3^2)\\KE=3^2\\KE=9J[/tex]

The kinetic energy of the body is 9J

Kinetic energy is the energy possessed by a body due to its motion.

It is claculated by formula,

K.E = [tex]\frac{1}{2}mv^{2}[/tex]

Here,

The mass of the body = 2.0kg

speed = 3.0m/s

So kinetic energy K.E = [tex]\frac{1}{2}mv^{2}[/tex]

K.E = [tex]\frac{1}{2} (2)3^{2}[/tex] = 9J

So the kinetic energy of the body is 9J

Explanation:

Answer:

Energy transferred, Q = 20790  J

Explanation:

Given that,

The change in temperature of the liquid, [tex]\Delta T = 15^{\circ} C[/tex]

The mass of liquid, m = 0.33 kg

The specific heat capacity of the liquid is 4200 J/kg°C.

We need to find the energy transferred from the liquid as it cools. The energy transferred is given by :

[tex]Q=mc\Delta T\\\\Q=0.33\times 4200 \times 15\\\\Q=20790\ J[/tex]

So, 20790  J of energy is transferred from the liquid as it cools.

Answer:

THE MASS OF THE LIQUID IS 22.5 g

Explanation:

Density = 0.180 g/cm3

Side length = 5 cm

Mass = unknown

To calculate the mass of the liquid, we use the formula:

Mass = density * volume

Volume of a cube or cuboid container = l^3

Volume = 5 ^3 = 125 cm3

So therefore, the mass of the liquid is:

Mass = 0.180 * 125

Mass = 22.5 g

In conclusion, the mass of the liquid in the container is 22.5 g

Answer:

When two objects are in thermal equilibrium they are said to have the same temperature. During the process of reaching thermal equilibrium, heat, which is a form of energy, is transferred between the objects.

The velocity is 17 m/s South.

Answer:

17

Explanation:

Explanation:

Given

force (F) = 75 N

Acceleration (a) = 5 m/s²

Mass (m) = ?

We know

F = m * a

75 = m * 5

m = 75 / 5

m = 15 kg

The mass of the shopping cart is 15 kg.

Answer:

Air outside the cup affect the kinetic energy of the particles in the wall and the cold water by transferring its heat to the cup and cold water.

Explanation:

The air outside the cup has a high temperature as compared to that of the cold water with in the cup.

As this hot and moist air it comes in contact of cup, it transfers its heat energy and become cool itself thereby leaving water droplet on the outer side of the cup.

Due to heat imparted to the cup, the atoms with in the cup and cold water starts vibrating and hence there kinetic energy increase.

Answer:

The force of the bat is pushing harder than the ball. When there are unbalanced forces, one will move less or more than the other. Balanced forces stay the same force, that's why they're call "balanced" forces. so in this example, the bat has a stronger force than the ball, which causes the ball to have a greater reaction

The following statements are true about an object in two-dimensional projectile motion with no air resistance

D) The speed of the object is zero at its highest point.

E) The horizontal acceleration is always zero and the vertical acceleration is always a non-zero constant downward

Explanation:

A) The speed of the object is constant but its velocity is not constant.

False the vertical velocity increases on descent

B) The acceleration of the object is constant but its object is + g when the object is rising and -g when it is falling.

False, the acceleration is -g when the object is rising

C) The acceleration of the object is zero at its highest point.

False, the acceleration is constant in magnitude throughout the motion

D) The speed of the object is zero at its highest point.

True, the direction of motion changes at the highest point from hence the body comes to rest and the speed is zero

E) The horizontal acceleration is always zero and the vertical acceleration is always a non-zero constant downward

True, the horizontal acceleration has associated force during motion but the vertical acceleration is due to gravity which is constant downwards

Two masses oscillating together with each of their time period as ,'T'

Option B

we know that,

The time period of a mass 'm' on a spring of spring constant 'k' can be strategize by the following equation :

[tex] \huge \rightarrow \: T \: = 2π \sqrt{ \frac{m}{k} } [/tex]

According to the question,

so,

The new time period would be

[tex] \huge \rightarrow \: T ' \: = 2π \sqrt{ \frac{2m}{2k} } [/tex]

[tex] \huge \rightarrow \: T ' \: = 2π \sqrt{ \frac{m}{k} } [/tex]

[tex] \huge \rightarrow \: T ' \: = T[/tex]

Hence ,option B is correct ✓
