Walking converts what type of energy into mechanical energy?

2 answers:

8 0

The answer is chemical energy.

In our body, our chemical energy comes in the form of glucose. It is glucose that is turned into mechanical energy in our body. When we move, our muscles act as a transducer. As muscles contract, they convert the glucose in our body into mechanical energy. The mechanical energy in our muscles is also called muscular energy.

The correct answer is chemical energy. Walking converts into a chemical energy which is a type of mechanical energy. Chemical energy is the energy stored in the chemical compound bonds and mostly released by the chemical reaction which will produce heat.

As you heat a steak on a grill, what kind of energy are you increasing in the steak?

katrin2010 [14]

The correct answer to the question above is Thermal Energy. As you heat a steak on a grill, the kind of energy that you are increasing is Thermal Energy. Thermal energy is the energy that come from heat, since you are you grilling the steak which means there is fire underneath, it has thermal energy.

At a particular instant, an electron moves toward the east in a uniform magnetic field that is directed straight downward. the m

alexdok [17]

Answer:

towards the south

Explanation:

When the electron enters the region with magnetic field, it experiences a magnetic force perpendicular to both the directions of the electron's velocity and the magnetic field.

The direction of the force exerted on the electron can be found by using the right-hand rule:

- Index finger: direction of the velocity of the electron --> towards the east

- Middle finger: direction of the magnetic field --> downward

- Thumb: direction of the force on a positive particle --> towards the north

However, the electron is a negatively charged particle, so we must reverse the direction of the force: therefore, the force exerted on the electron is towards the south.

A student sets up an experiment to determine the inertial mass of a cart. The student has access to the following measurement eq

wlad13 [49]

Answer:

The correct answers are a and d

Explanation:

In this experiment it can be analyzed using Newton's second law

F = m a

m = F / m

The outside is supplied by the spring balance and is constant, therefore the acceleration of the system is also constant.

The acceleration can be found with the kinematic equations

x = v t + ½ a t²

As we start from rest the initial speed is zero

a = 2 x / t²

Therefore we need the reading of position and time.

Finally, the relationship between the balance reading and this acceleration of the mass of the system

Let's analyze the answers

a) True. It is one of the necessary quantities

b) False. With the equipment we cannot measure the speed directly

c) false. Acceleration is calculated

d) true. It is the other magnitude necessary for the calculation.

The correct answers are a and d

If you place 0◦C ice into 0◦C water in an insulated container, what will the net resultbe? Will there be less ice and more liqui

Airida [17]

Answer:

The amounts will stay the same.

Explanation:

We have a case here. O°C ice into O°C water in an insulated container. The poser here is that what would be the net effect.

It must be highlighted that the insulated container is parody of a constant room temperature and pressure. Meaning all factors are held constant.

Also, a O°C ice is simply the same as a O°C water. Hence, viewing the question under this context, and also acknowledging the constant environment, tells us that the two - Ice and Water at such temperature, will remain unchanged. The effect will be neural.

The underlying factor is that both substances are subjected to same conditions. Hence, the latent kinetic energy and other molecular movements that could occasion will be doing so at same level and frequency. Thus, producing a neutral or almost non different result.
