The charges may be positive or negative. However, the behavior of the charges depend on the position of like charges and unlike charges.

An electrical charge may be positive or negative. We must recall that a charge may attract or repel another charge. According to the first law of electrostatics, like charges repel while unlike charges attract.

Given what we know, we can confirm that electroconvulsive therapy has been most successful in the treatment of major depression.

This is a relatively new procedure. It involves the intentional triggering of brief seizures in the brain. This is done while the patient is under the effects of anesthesia and is therefore painless. These seizures cause a dynamic shift in the brain chemistry of the patients, leading to greatly reduced symptoms in over 80% of patients.

Therefore, we can confirm that electroconvulsive therapy has been most successful in the treatment of major depression.

The store associated with the energy when a ball has 10 J of energy when it is 1 m above the floor is gravitational potential energy

Gravitational potential energy is the energy of a body by virtue of its position in the gravitational field.

From the question, If a tennis ball has 10 J of energy when it is 1 m above the floor, first, a work of 10 J was done against gravity to lift the tennis from the floor to a height of 1 m. At the height of 1 m, the work of 10 J is converted to the gravitational potential energy of the tennis ball which is stored in the ball.

Hence, The energy associated when a tennis ball has 10 J of energy and it is 1 m above the floor is gravitational potential energy.

In the thermal equilibrium, the change in temperature is said to be zero in between the bodies. Thermal equilibrium is reached when both objects have the same temperature.

Thermal equilibrium is easily explained by the zeroth law of thermodynamics. If any two-body is at thermal equilibrium there is no change in the temperature of the body.

According to zeroth law if body A is in thermal equilibrium with body B and body B is in thermal equilibrium with C . So body A and C are also in thermal equilibrium.

In the thermal equilibrium, the net heat transfer is said to be zero in between the bodies.

Hence option A IS RIGHT. Thermal equilibrium is reached when both objects have the same temperature

110=100.c.(70-60)

c=0.11

Answer:

110 cal kg⁻¹°C⁻¹

Explanation:

Formula to find the specific heat capacity is :

Q = m c Θ

Here,

Q = heat energy

m = mass

c = specific heat capacity

Θ = change in temperature

Now let us find the specific heat capacity now.

Q = m c Θ

110cal = 1kg × c × (70 - 60 ) °C

110cal= 0.1kg × c × 10°C

110 =  1 c

Divide both sides by 1.

c = 110 cal kg⁻¹°C⁻¹
