Answer:
A
Explanation:
A dynamic equilibrium is a chemical equilibrium between a forward reaction and the reverse reaction where the rate of the reactions are equal.
The rate of the forward reaction equals the rate of the backward reaction.
For a system to be in dynamic equilibrium, the forces should be balanced.
What is dynamic equilibrium?According to chemistry, Dynamic equilibrium is all about the equal rate of change in reactants and products, i.e., there will be a steady state. Also in Physics, if though the number of the composition of mixtures happens and that does not change with time, i.e., it is equilibrium constant. For example, when the car moving on the road, there will be some friction. The forward force of the car happened due to friction but no other force has changed at car's constant speed. When the net force will be same then it is known to be dynamic equilibrium.
Equilibrium constants can be determined as rate constants through reversible reaction, i.e., the rate of the forward reaction equals to the rate of the backward reaction.
Thus, option A is correct.

"How does mass affect thermal energy transfer?
Answer:
The greater the mass of a substance the more thermal energy. The thermal energy of a substance depends on the temperature and mass of that substance.
Explanation:
Answer:
Explanation:
If two objects have the same mass, the object with the higher temperature has greater thermal energy. Temperature affects thermal energy, but temperature isn't the same thing as thermal energy. That's because an object's mass also affects its thermal energy.

Answer:
Cools ; size
Explanation:
The rate at which magma cools determines the size of the crystals in the new rock. Igneous rocks are formed from the cooling and solidification of molten magma which finds its way to the surface or depth of very low pressure beneath the surface. This place or depth of cooling of magma affects the cooling rate and hence the size of the crystals formed. Igneous rocks formed at depths below the surface have more time to cool and allows more time for Crystal growth and hence produce coarse grained crystal grains called Intrusive igneous rocks which have significantly larger crystals than those formed on the surface which cools rapidly and allowing very little time for crystal growth giving rise to the formation of fine grained crystals and are called extrusive igneous rocks.
A -0.00125 C charge is placed 3.62 m from a +0.00333 C charge. What is the magnitude of the electric force between them?
Remember, magnitudes are positive.
[?] N
Answer: 2858.7726N
Explanation:
Given that :
Charge 1 (q1) = -0.00125 C
Charge 2 (q2) = +0.00333 C
Distance (r) = 3.62 m
According to columb's Law: The magnitude of the force between any two charged objects :
Fe = (Kq1q2) / r^2
Coloumb's constant(k) = 9×10^9 Nm^2/C^2
Fe = (9×10^9 * 0.00125 * 0.00333) / 3.62^2
Fe = (0.0000374625 * 10^9) / 13.1044
Fe = 37462.5 / 13.1044
Fe = 2858.7726N

a ball is projected with a certain angle with initial velocity u. it covers horizontal range R. With what initial velocity it must be projected keeping the angle of projection same so its horizontal range becomes 2.25R
Answer:
1.5 u
Explanation:
The range equation is:
R = u² sin(2θ) / g
When u = v, R = 2.25 R.
2.25 R = v² sin(2θ) / g
2.25 u² sin(2θ) / g = v² sin(2θ) / g
2.25 u² = v²
1.5 u = v
If 400 joules of heat are added to a gas in an isochoric process, what is the
change in its internal energy?
O A. 400 J
O B.-400 J
O C. 100 J
OD. 200
Answer:
A. 400 J
Explanation:
Because the process is isochoric, no volume change, so no work, so none of the energy is lost or converted. In other words, the system will gain and hold onto all of the J of heat put into it, which was 400J
A boy on a chairlift moving parallel to the mountain slope at a speed of +15 m/s watches a skier going straight down the mountain with a speed of -35 m/s. What is the velocity of the skier relative to the chairlift? A. -50 m/s B. -35 m/s C. -20 m/s D. +15 m/s E. +50 m/s
Answer:
A. -50 m/s
Explanation:
Given
Velocity of Chairlift = +15m/s
Velocity of Skier = -35m/s
Required
Determine the velocity of the skier relative to the chairlift
Basically, relative velocity is the difference between the two velocities;
Having said that;
Relative velocity of the skier relative to the chairlift = Velocity of the Skier - Velocity of the Chairlift
Relative velocity of the skier relative to the chairlift = -35m/s - (+15m/s)
Open bracket
Relative velocity of the skier relative to the chairlift = -35m/s - 15m/s
Relative velocity of the skier relative to the chairlift = -50
