q or heat transfer when 5.88 g of ice is cooled from -21 °c to -118 °c is

1171J.

The equation q = mLΔT is used to calculate the heat transfer, or q, in a thermodynamic process. The equation states that the heat transfer, q, is equal to the product of the mass, m, of the substance being heated or cooled, its specific heat capacity, L, and the change in temperature, ΔT.

The specific heat capacity, L, is a measure of the amount of heat required to raise the temperature of one kilogram of a substance by one degree Celsius. It is a constant value for a given substance and depends on its molecular structure and physical properties.

The change in temperature, ΔT, is the difference between the initial and final temperatures of the substance, and it represents the amount of temperature change that has occurred during the process.

Therefore, the equation q = mLΔT can be used to determine the amount of heat transfer that occurs when a substance is heated or cooled, by multiplying its mass, specific heat capacity, and the change in temperature. The units of heat transfer are typically joules (J).

In this case, q = (5.88 g)(2.09 J/g°C)(-118°C - (-21°C))

q = (5.88 g)(2.09 J/g°C)(97°C)

q = 1171 J

So the heat transfer, q, is 1171 J.

The probability of the freeman's hit is 0.76 if he hits 38 out of his 50 pithes.

Another meaning of probability is possibility. It is a topic of mathematics that deals with the chances of occurrence of a random event. The value varies from zero to one. Probability is introduced in Maths to predict or estimate how likely events are to happen. The meaning of probability is basically the chances of being successful of an event in a number of trial. This is the basic concept of probability theory. This is also used in the probability distribution, where we learn the possibility of results for a random experiment. To find the probability of an event to occur, first, we should know the total number of possibilities, in favor or in against.

A particle of mass 4kg initially moving with a velocity of 2m/s collides elastically with a particle of mass 6kg initially moving with a velocity of -4m/s. Then the final velocity of the 4kg mass is -26/5 m/s.

Since the collision is an elastic collision, so there is no loss in kinetic energy. The value of e is 1. Taking the right side as positive and the left side to be negative as the sign convention. Initially the speed of the 4kg mass of the block =2m/s (left to right). The speed of the 6kg block =4m/s (right to left). Let the speed of the masses after a collision to be v₁ and v₂ respectively (left to right both). According to the law of  Conservation of momentum,  P (initial)= P (final), (4×2)-(6×4) = (4×v1) + (6×v₂),( 2×v₁)+(3×v₂)=-8 _____(eq i).

Now from equations (i) and (ii), we have 5×v₂=4, v₂=⅘ m/s. Since the value of v₂ is positive so it means that it moves from left to right. Putting the value of v₂ in eq (ii), we get, v₁=-26/5 m/s.Since the value of v₁ is negative so it moves from right to left.

The value of the coefficient of static friction always must be > 0 otherwise the coefficient can't be a friction coefficient.

What is friction ?

Friction is a force that opposes motion between two objects in contact. It arises due to the roughness of the surfaces in contact and the interlocking of their microscopic irregularities. Friction can be either static (when the two objects are not moving relative to each other) or kinetic (when the two objects are sliding or moving relative to each other). The magnitude of the friction force depends on the surface roughness, the normal force, and the coefficient of friction between the two surfaces.

The electrons rather than protons are the principal charge carriers in metal wires because electrons are free to move through the metal, whereas protons are fixed in place.

Electrons are negatively charged particles, whereas protons are positively charged particles. In metals, electrons are free to move and flow, making them the main charge carriers. On the other hand, protons are firmly fixed within the atomic nuclei of the metal, meaning that they are not free to move or flow.

If you were suddenly transported to a planet with the same radius but twice the mass as earth, the force of gravity acting on you would change. This is because the force of gravity depends on the mass of the object you are near and the distance between you.

This force is a result of the mass of an object and its distance from another object with mass. The closer two objects are to each other, the stronger the force of gravity between them. On this new planet, you would still be the same distance from its centre, so the radius would not affect the force of gravity. However, because the planet has twice the mass of Earth, the force of gravity would be stronger.

To be more precise, the force of gravity is proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between them. This means that if the mass of one object doubles, the force of gravity between them will increase by a factor of four. In this case, because the planet has twice the mass of Earth, the force of gravity acting on you would be four times stronger than it is on Earth.

If no forces are acting on an object, it will continue to move with a constant velocity.

It will not change its speed or direction unless acted upon by a force. This concept is known as Newton's First Law of Motion or the Law of Inertia. Therefore, if an object is already in motion with a constant velocity and there are no forces acting on it, it will continue to move. However, if the object was initially at rest, it will remain at rest, as it requires a force to start it moving. An item at rest will remain at rest, and an object in motion will continue to travel with a constant speed in a straight line, according to Newton's First Law of Motion, often known as the Law of Inertia.
