Answer:

when molten rock cools above the earth's surface

Explanation:

Extrusive Igneous Rocks Extrusive igneous rocks are formed when molten magma spill over to the surface as a result of a volcanic eruption. The magma on the surface (lava) cools faster on the surface to form igneous rocks that are fine-grained.

Answer:

The wedge balances propelled force.

Explanation:

According to the laws of motion, when appropriate weight is employed properly, a ball can move a truck. The same basic functions apply in this scenario. You often find a woodcutter raising the axe and letting it fall into the wood. This allows force to equally generate at both sides of the axe, splitting the wood apart.

Answer:

341.46miles

Explanation:

Find the diagram attachment.

To get the displacement D, we will use the cosine rule as shown;

D² = 200²+150²-2(160)(400)cos65°

D² = 40000+22500-128000cos65°

D² = 62500+54095.14

D² = 116595.14

D = √116595.14

D= 341.46 miles

Hence the plane final displacement is 341.46miles

A skateboarder rolls horizontally off the top of a staircase and lands at the bottom. The staircase has a horizontal length of 12.0 m with a vertical drop of 2.00 m. We can ignore air resistance.

What is the skater's initial horizontal velocity?

Answer: 18.8 m

Answer:

the acceleration is negative which means it is going in the opposite direction of the actual motion which concludes the reason why the ball is slowing down. However, when the ball is stopped, there is no acceleration as the ball is in equilibrium

Answer:

Force = 533.33N

Explanation:

Given the following data;

Power = 40000watt

Velocity = 75m/s

To find the force;

[tex] Power = force * velocity [/tex]

Making force the subject of formula, we have;

[tex] Force = \frac {Power}{velocity}[/tex]

[tex] Force = \frac {40000}{75} [/tex]

Force = 533.33N

Answer:

Kinetic energy depends on mass and speed (or magnitude of velocity).

K.E.  = 1/2 M S² or The amount of kinetic energy of a moving object has dependence on its  mass and its velocity.

Explanation: They are both right for a certain question

The kinetic energy of a moving object depends on its mass and velocity. The higher the velocity higher will be the kinetic energy. Mass also have the similar effect.

Kinetic energy of an object is the energy generated by virtue of its motion. When particles of an  object acquire much energy to overcome the intermolecular force, they gain kinetic energy to move apart.

Kinetic energy is related to the mass and velocity of the moving object. The expression relating kinetic energy with these parameters is written below:

Ke = 1/2 mv².

As per the relation, the kinetic energy of an object increases with an increase in mass or velocity or both. Hence, massive objects with greater velocity is having greater kinetic energy.

Answer:

Neon (Ne), chemical element, inert gas of Group 18 (noble gases) of the periodic table, used in electric signs and fluorescent lamps. Colourless, odourless, tasteless, and lighter than air, neon gas occurs in minute quantities in Earth's atmosphere and trapped within the rocks of Earth's crust.

Explanation:

I am smart

Answer:

It is a Noble gas and its group is 18 or 8a and its period is 2.

Explanation:

the reason behind my answer is group is the column and the period is the row.

Answer:

a i. The higher curve is "thick wall" and the lower curve is "thin wall".

a ii. The thicker the wall, the more time it takes to transfer the same amount of heat. Thus, the thick wall would have a less steep drop in temperature as it transferred lesser heat from the room to the surroundings and the thinner wall would have a steeper drop in temperature as it conducted more heat away from the room to the surroundings.

Answer:

Mechanical energy is constant and it remains the sum of the potential and kinetic energies in a system.  

In the system, we have inverse relation between potential and kinetic energies so it will make mechanical equal

Answer:

B) is the answer

Explanation:

A) is 25 N

B) is 36N

C) is 30N

D)15N

Answer:

29.4N is a 3.0kg bag of bolts weigh.

The force by gravitation is called the weight of a body. The weight of the body with a mass of 3 Kg is 29.4 N.

Gravitational force is a kind of force by which an object attracts other objects into its center of mass. Earth attracts every objects into its center and thereby we are all standing on the surface.

Gravitational force is acting downward on a body and it depends on the mass of the body. Greater the mass, greater will be the fore of gravitation and its weight experienced on earth.

Given that, mass of the bag = 3 Kg.

force by gravitation  = Mg = 3 × 9.8 m/s² = 29.4 N.

where, g is the acceleration due to gravity. Therefore, the weight of the bag is 29.4 N. Hence, option D is correct.

#SPJ2

Answer:

The one that is 100 cm from the center.

Explanation:

Given that merry-go-round means moving at uniform circular motion or constant angular speed. Hence the person who is closer to the center is moving at a slower speed, while the one far away from the center has a larger linear speed because he has moved a long distance in the same amount of time, despite being on these objects.

To illustrate

A with the 50 cm

B with the 100 cm

Hence, to get speed, we have

A = 2 * pi * 50 / T

B = 2 * pi * 100 / T

And by the explanation of angular speed

We have w = 2*pi/T where w is the angular speed in radians/s

Hence we have

A = 50w

B = 100w

Therefore, the one that is 100 cm from the center has a larger linear speed.

Explanation:

Step one:

given data

mass of red cart m1=0.5kg

initial velocity u1 of red cart=50cm/s

mass of blue cart m2=0.5kg

initial velocity u2 of blue cart= 0cm/s

final velocity v2 of blue cart= 40cm/s

final velocity v1 of red cart= 10cm/s

Step two:

Momentum values red cart before and after the collision.

Before collision

P1=m1u1

P1=0.5*50

P1=25kg•cm/s

After collision

P2=m1v1

P2=0.5*10

P2=5kg•cm/s

Change in momentum= P1-P2=25-5= 20kg•cm/s

Momentum values blue cart before and after the collision.

Before collision

P1=m1u1

P1=0.5*0

P1=0 kg•cm/s

After collision

P2=m1v1

P2=0.5*40

P2=20kg•cm/s

Change in momentum= P1-P2=0-20= -20kg•cm/s

The total momentum of the system of the carts before collision is 25 kgcm/s.

The total momentum of the system of the carts after collision is 25 kgcm/s.

The change in momentum of the red cart is -20 kgcm/s.

The change in momentum of the blue cart is 20 kgcm/s.

The given parameters;

The momentum of the red cart before collision is calculated as follows;

[tex]P_r_1 = m_1u_1\\\\P_r_1 = 0.5 \times 50\\\\P_r_1 = 25 \ kgcm/s[/tex]

The momentum of the blue cart before collision is calculates as follows;

[tex]P_b_1 = m_2 u_2\\\\P_b_1 = 0.5 \times 0\\\\P_b_1 = 0 \ kgcm/s[/tex]

The momentum of the red cart after collision is calculated as follows;

[tex]P_r_2 = 0.5 \times 10\\\\Pr_2 = 5 \ kgcm/s[/tex]

The momentum of the blue cart after collision is calculated as follows;

[tex]P_2b_2 = 0.5 \times 40\\\\P_2b_2 = 20 \ kgcm/s[/tex]

The total momentum of the system before and after collision is calculated as follows;

[tex]P_1 = 25 \ kgcm/s \ + \ 0 = 25 \ kgcm/s\\\\P_2 = 5 \ kgcm/s \ + \ 20 \ kgcm/s = \ 25 \ kgcm/s[/tex]

The change in momentum of the red cart is calculated as follows;

[tex]\Delta P_r = Pr_2 - Pr_1\\\\\Delta P_r = 5 - 25 = - 20 \ kgcm/s[/tex]

The change in momentum of the blue cart is calculated as follows;

[tex]\Delta P_b = P_b_ 2 - P_b_1\\\\\Delta P_b = 20 - 0 \ = \ 20 \ kgcm/s[/tex]
