The speed on a car speedometer. Is it speed or velocity? Explain Why
Sliva [168]
Velocity is a speed AND a direction.
When you turn a corner, or go around a curve in the road, your
direction changes, but the reading on the dial doesn't change.
So it can't be showing velocity.  It must be showing only speed.
That's probably a big part of the reason why it's called a speedometer
and not a velocimeter.

If 5000Pa a pressure is exerted on an object with the contact area 0.04m^2. Calculate the mass of an object
Whitepunk [10]
  • Pressure = 5000 Pa
  • Contact Area = 0.04 m^2
  • Acceleration due to gravity = 9.8 m/s^2
  • Let the force be F.
  • We know, Force = Pressure × Contact Area
  • Therefore, Force = 5000 Pa × 0.04 m/s^2
  • or, Force = 200 N
  • We know, force = mass × acceleration
  • Therefore, mass = force ÷ acceleration
  • or, mass = 200 N ÷ 9.8 m/s^2 = 20.4 Kg

How can students earn a GED
ElenaW [278]

Answer:

How Can You Earn Your GED?

  • You must be at least 16 years old to take the GED Test, and you must not be enrolled in high school. ...
  • You must pass all four subject tests in the GED battery of tests, which means scoring at least a 145 on each test (New Jersey requires a score of at least 150 to pass).

>Rules

You must be at least 16 years old to take the GED Test, and you must not be enrolled in high school. You should also meet state eligibility requirements for the amount of time you've been out of high school. In some states, you have to be out of high school for at least 60 consecutive days before you're allowed to take the test. Contact the program administrator in your state for more details.

You must pass all four subject tests in the GED battery of tests, which means scoring at least a 145 on each test (New Jersey requires a score of at least 150 to pass). Scores range from 100 to 200 on the 2014 version). A score of 165 on each test is the benchmark for college and career readiness, and you will receive an Honors distinction if you reach this score. The four tests take seven and a half hours total and are administered by computer. You don't have to take them all on the same day, but some states enforce specific time frames for completing the tests. Most questions are multiple choice, although there is also a mix of fill-in-the-blank, drag and drop, and select-an-area questions, as well as an essay question on the Reasoning Through Language Arts section.

If you don't pass a test the first time around, you can retake it, although different states have different requirements for people who need to retake GED tests (such as additional fees or proof of attending a preparation class). Testing accommodations are available for those with disabilities; you can sign up for them through your online account after you register. You usually have to pay to sign up for the tests, but the cost varies from state to state. After you take each test, you will receive your scores within 24 hours. Here are some more details about the score report.

A ball is thrown upwards and returns to the same location. Compared with its initial speed its speed when it returns is about___
Strike441 [17]

Answer:

Explanation:

Let the ball is thrown upwards with speed u and reaches upto height h.

Use III equation of motion

v^{2}=u^{2}-2gh

here, final velocity v = 0

So, u = \sqrt{2gh}

Now as the ball reaches the maximum height, it starts falling freely. Let it strkes with the ground with velocity v'.

v'^{2}=u^{2}-2gh

here, u = 0

So, v' = \sqrt{2gh}

It means the velocity is same as the velocity of projection.

uranmaximum [27]

Answer:

The magnitude of force exerted on the handle is 108.73 N

Explanation:

To determine the magnitude of force exerted, we will use the formula relating Power and Force.

Power is the rate at which work is done. Power can be calculated from the formula

Power = Work / Time

But, Work = Force × Distance

Hence,

Power is given by the formula

P = \frac{F \times s}{t}

Where P is the Power

F is the force

s is the distance

and t is the time

From P = \frac{F \times s}{t},

Then we can write that

F = \frac{P \times t}{s}

From the question,

Distance, s = 1.1 m

Time, t = 1.3 s

Power, P = 92 W

Putting these values into the formula, we get

F = \frac{92 \times 1.3}{1.1}

F = \frac{119.6}{1.1}

F = 108.73N

Hence, the magnitude of force exerted on the handle is 108.73 N.
