Answer:

The object will have an acceleration and the object's velocity will change.

Explanation:

If there is a net force acting on an object, the object will have an acceleration and the object's velocity will change. Newton's second law states that for a particular force, the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object.

Answer:

H = Vo t + 1/2 g t^2

Velocity and gravitational acceleration are vector quantities - it is very important to use the correct signs for these quantities to get the correct quantity for H the distance traveled.

Answer:

Answer:

279 m/s

Explanation:

Answer:

2m/s^2

Explanation:

A=(u-v)/t

where u=final velocity and v=initial velocity and t=time

therefore u =70 and v=0 because the question said velocity of rest and finally t=35

so, (70-0)/35= 70/35=2

The best description of the role of glucose in the body is that it is the food converted into fuel. Details about role of glucose can be found below.

Cellular respiration is the process by which living organisms obtain energy for their daily activities by breaking down food molecules in their cells.

The food ingested by living organisms is digested into the simplest form called glucose. The glucose is then broken down during cellular respiration.

During cellular respiration, glucose is broken down to produce energy (ATP), which is the fuel for metabolic activities in the body.

Answer:

The force by which a substance (magnet) attracts a body(metals) towards it is called magnetic force

Answer:

Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.

Explanation:

The gravitational potential energy of a falling apple is similar to the potential difference of a battery because both are energy stored in the object

The gravitational potential energy of a falling apple is maximum when the apple is at maximum height. As the apple begins fall to the ground the potential energy decreases and it will be transformed to kinetic energy.

[tex]P.E_i + K.E_i = P.E_f + K.E_f[/tex]

The potential difference in a battery is total energy stored in the battery.

Thus, the gravitational potential energy of a falling apple is similar to the potential difference of a battery because both are energy stored in the object.

The similarity is that both the battery and the falling apple have stored energy.

We define the potential energy of an object as stored energy in that object.

A battery has potential energy, it is stored until you connect it to something and allow that energy to flow.

Similarly, when the apple is in the air it has potential energy, that will be transformed into kinetic energy as it falls (as the apple falls, its velocity increases, thus, the kinetic energy increases).

So both, the apple and the battery have stored energy, and that is the similarity between these two.

Answer: When air passes both above and below the airfoil, the air on top moves faster because of the curve, causing it to have a lower air pressure. This is according to Bernoulli’s principle, which states that faster moving air has less pressure than slower moving air. Also This is what causes the airplane to lift into the air.

Explanation:

Answer:

it pulls on the air above it accelerating that air down

The relation of uniform movement allows to find the result for the distance that descended when crossing the river is:

           d = 180 m

Given parameters

To find

Velocity is a vector magnitude, it has modulus and direction, therefore vector algebra must be used.

The velocities are constant, let's use the uniform motion relation.

           v = [tex]\frac{d}{t}[/tex]  

In the attached we have a diagram of the movement.  Let's calculate the time to cross the river.

          [tex]v_r = \frac{x}{t}[/tex]  

            [tex]t= \frac{x}{v_r}[/tex]  

            t = [tex]\frac{120}{8.0}[/tex]  

            t = 15 s

The time is a scalar it is the same for the two movements, let's find how much it has descended in this time.

          [tex]v_m = \frac{d}{t}[/tex]  

           d = [tex]v_m t[/tex]  

           d = 12.0  15

           d = 180 m

In conclusion, using the uniform motion relationship we can find the result for the distance that descended when crossing the river is:

           d = 180 m
