Answer:

Temperature decreases as depth increases (generally)

Explanation:

In general, sunlight will heat the upper level of water.  As you go deeper into the water, the sunlight cannot reach as easily so the temperature is lower.

There are exceptions considering underwater currents like the Gulf Stream or volcanic vents.

Explanation:

Friction always slows a moving object down. ... Friction can be a useful force because it prevents our shoes slipping on the pavement when we walk and stops car tyres skidding on the road. When you walk, friction is caused between the tread on shoes and the ground. This friction acts to grip the ground and prevent sliding.

Answer is 4 m/s

Let :-

Constant velocity = v

Time (t) = 2 seconds

Height (h) = 16 metres

As the raindrop has constant velocity, we can write that :

[tex] \frac{h}{2} = vt[/tex]

Substituting the values, we get,

[tex] \frac{16}{2} = v \times 2[/tex]

[tex]8 = v \times 2[/tex]

[tex] \frac{8}{2} = v[/tex]

[tex]v = 4 \: m/s[/tex]

Therefore, the velocity of the raindrop is 4 m/s.

Answer:

static friction

Explanation:

F = F⁰ - Ff

F = 360 N - 340 N

F = 20 N

F = m × a

20 N = 50 kg × a

a = 20 N / 50 kg

a = 0.4 m/s²

#LearnWithEXO

The acceleration of the box when the frictional force of 340 N is applied to the box will be 0.4 m/s².

In mechanics, acceleration is the measure of how quickly the velocity of an object changes with respect to time. The magnitude of accelerations as a vector. The acceleration of an object depends on the direction of the net force acting on it.

It is a vector quantity because acceleration has both a magnitude and a direction. Additionally, velocity is a vector quantity. The change in the vector of velocity during a period of time divided by the period of time is the definition of acceleration.

According to the question,

F = F⁰ - [tex]F_f[/tex]

F = 360 N - 340 N

F = 20 N

Force = m × a

20 N = 50 × a

a = 20 N / 50 kg

a = 0.4 m/s²

So, the acceleration of the box will be 0.4 m/s².

Answer:

Final velocity = 7.4m/s

Explanation:

Use the equation:

acceleration = (final velocity - initial velocity)/time

Rearrange to get:

final velocity = (acceleration * time) + initial velocity

Now just substitute with the values you already have:

Final velocity = (-9.8m/s^2 * 0.7s) + 0.5m/s

Final velocity = 7.36m/s

We are using 2 sig-figs, so:

Final Velocity = 7.4m/s

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.

Explanation:

It is a change in the distribution of electric charge on one object because of  the influence a nearby object that has an electric charge.  So if an object with a negative charge is brought near to a neutral object, the neutral object will alter itself so that one side becomes more positive and the other side becomes more negative.

Electrostatic induction occurs whenever any object is placed in an electric field.

The acceleration is approximately 4 m/s². Therefore, the correct answer is:

A. 4 m/s²

To determine the acceleration from the graph, we need to look at how the velocity changes over time. Acceleration is defined as the rate of change of velocity with respect to time. In other words, it is the slope of the velocity-time graph.

Looking at the graph, we can see that the velocity changes from 0 m/s to 4 m/s over a time interval of 2 seconds. To calculate the acceleration, we use the formula:

Acceleration (a) = Change in velocity / Change in time

Acceleration (a) = (4 m/s - 0 m/s) / (2 s) = 4 m/s²

So, the acceleration is approximately 4 m/s². Therefore, the correct answer is:

A. 4 m/s²
