HELP MY GRADES-

If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you'll get the distance in miles to the lightning: 5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close. Keep in mind that you should be in a safe place while counting.

One of the ways to help someone not to be influenced by media is:

Encourage independent thinking.
Let her know that she should make sure the information she is consuming is free from bias and is factual.

<h3>What is Media Influence?</h3>

This refers to the effects and reactions which the mass media has on the people who listen to them by shaping their views and by controlling the narrative.

With this in mind, we can note that if a person is overtly influenced by the media, then such a person lacks independent thinking and becomes emotional by what he watches on the television or reads from an online source.

This can be changed through the encouragement of independent thinking, and the need to check for factual information from the media news and also to focus more on studies.

In the national grid,what does the step up transformer do?

amm1812

In the National Grid, the Step Up Transformer increases the amount of voltage that is passing through the grid at any one time. These are used at power stations, as without them, there would not be enough power to transport the electricity around the national grid.
Hope this helps :)

I don't know the answer can anybody help?

Anna007 [38]

We don't have enough information in the picture to answer that question.

The disembodied right hand could just as well grab the wire in the other direction, with the thumb pointing to the right.

Maybe if we knew WHY the hand is holding the wire in this direction, and what other electrical phenomenon may be involved, we might be able to say something about the current in the wire.

(Actually, we don't even know if it's a wire. It might be a soda straw, a coat hanger, or a pool cue.)

A uniform meter stick of mass $M$ has a half-filled can of fruit juice of mass $m$ attached to one end. The meter stick and the

Answer:

111.6 g

Explanation:

Given

m + M = 2.58 / 9.8

= 0.2632 kg

When the can of fruit juice is balance from scale , we get following relation

M x ( 50 - 21.2 ) = m x 21.2 ( balancing the torque due to weight of scale and can about the balancing point )

M x 28.8 = 21.2 m

= 21.2 ( 0.2632 - M )

= 5.58 - 21.2 M

M ( 28.8 + 21.2 ) = 5.58

M = .1116 kg

= 111.6 g

Students are using the experimental setup shown in the image in which the two ends of a string are attached to a car and to a ha

AlekseyPX

The Newton's second law and kinematics allows to find the result of the error when placing the masses in the car is:

Acceleration decreases.

The plot of position vs. time squared is still linear, but the slope is less.

Newton's second law gives a relationship between the net force, mass and acceleration of the body

F = ma

a = $\frac{F}{m}$

Where F is the force, m the mass and the acceleration

Kinematics studies the motion of bodies, looking for relationships between position, velocity, and acceleration.

x = v₀ t + ½ a t²

In the experiment, the position and time of the car are measured, starting from rest in each experiment.

x = ½ a t²

Let's substitute

x = ½ ( $\frac{F}{m}$ ) t²

This is the equation that the students should graph, a graph of the position versus time squared can be made to obtain a line.

The slope of the line is the acceleration of the car, which is related to the force that is the weight of the hanging mass.

When the student makes the mistake of placing the mass on the car, the acceleration decreases therefore in a graph the position values are smaller for each time.

The linearity of the graph is maintained, but when calculating the slope it gives lower values.

In conclusion using Newton's second law and kinematics we can find the result of the error when placing the masses on the car is:

Acceleration decreases.

The plot of position vs. time squared is still linear, but the slope is less.
