Answer:

nodding of head ,yes- static equilibrium

nodding of head, no- dynamic equilibrium.

Explanation:

static equilibrium monitors head position when body is not moving .

dynamic equilibrium monitors the angular or rotational movements of the head when body moves.

Answer: Static equilibrium is simply described as one in which all forces acting on an object are balanced which implies that there is no resultant forces. And the object is not in motion releative to the reference plane.i.e the object does not have a velocity.

While

Dynamic equilibrium is type of equilibrium in which all the forces acting on an object are balanced but the object it moving, i.e there exist a veleocity.

Explanation:

Equilibrium simply means, forces are in balance. i.e the net force should be zero.

It can further explained forces acting downward and acting upward, and forces acting right and acting left should be equal in magnitude.

1) dynamic equilibrium can be described as the one in which the reactants are converted to products and products are converted to reactants at an equal and constant rate. Equilibrium is the state of equal, opposite rates, not equal concentrations.

Examples of dynamic equilibrium are; a)a car moving at constant velocity, b)a fan rotating at uniform speed

2)Static equilibrium is the one in which the rate of forward process is equal to reverse process.It is usually regarded as MECHANICAL EQUILIBRIUM because it occurs when all particles in the reaction are at rest and there is no motion between reactants and products.

Static equilibrium can be noticed when there is a steady-state in a system that is the dynamic forces are not acting on the potential energies of the reverse and forward reactions.

An example of static equilibrium is when graphite turn into diamond, and it is illustrated as

C(diamond) ⇌ C(graphite)

Vector A = 50 m,<br> 20°. Vector -3A would be equal to
Kruka [31]

Answer:

Many familiar physical quantities can be specified completely by giving a single number and the appropriate unit. For example, “a class period lasts 50 min” or “the gas tank in my car holds 65 L” or “the distance between two posts is 100 m.” A physical quantity that can be specified completely in this manner is called a scalar quantity. Scalar is a synonym of “number.” Time, mass, distance, length, volume, temperature, and energy are examples of scalar quantities.

A bird sits on top of a 639 m tall tower. If it's gravitational potential energy up there is 2033 J, what is its mass?
iris [78.8K]

The mass of the bird is 0.32 kg.

<u>Explanation:</u>

Gravitational potential energy, the energy exhibited by an object at rest due to the influence of gravitational force. So the increase in distance of object from the surface of earth leads to increase in the gravitational potential energy. Thus,

       \text {Gravitational potential energy}=m \times \text { Acceleration } \times \text { Distance of bird from bottom }

So, as the gravitational potential energy is given as 2033 J and the position of bird placed on the tall tower is 639 m away from the bottom, then the mass (m) of the bird can be found as below.

       m o f \text { bird }=\frac{\text {Gravitational potential energy}}{a \times \text {Distance}}=\frac{2033}{9.8 \times 639}=\frac{2033}{6262.2}

So, finally we get the bird's mass as,

            m of bird = 0.32 kg

A car in motion has kinetic energy. What happens to the kinetic energy when the car brakes to a stop? The kinetic energy is tran
Pie

Answer:

<em>When a moving car brakes to a stop the </em><em>kinetic energy of the car is converted to heat energy. </em>

Explanation:

A moving car has kinetic energy.

It is given by the equation k=\frac{1}{2} mv^2

Where m denotes mass of the car and v denote sits velocity. When the brakes are applied the velocity becomes zero and the car doesn’t possess kinetic energy anymore.

According to law of conservation of energy can neither be created nor be destroyed but can only be transformed from one form to another. On coming to a stop,  the kinetic energy of the car  gets converted to heat. The friction between the tyre and the road heats up the tyre.
