What is the strength of electric field EpEp 0.60 mmmm from a proton? Express your answer to two significant figures and include the appropriate units.

Answer:

Yes you  worked

Explanation:

You may have not seen a good outcome but you did put effort in.

When a force is applied on the car and it doesn't move then it simply means

work wasn't done.

The formula for work is given below:

Work = Force ₓ Displacement

For work to have been done , the applied force must cause the object to

change its position(displacement).

In situations where the force applied doesn't cause a change in position then work can't be calculated. This means no work was done on the car despite the applied force causing him to be tired.

Answer:

a) v = 141.9 m/s

b) v = 317.4 miles/h

Explanation:

a) How fast was he moving in meters per second?

[tex] v = \frac{d}{t} = \frac{1000 m}{7.045 s} = 141.9 m/s [/tex]

Hence, the jet ski is moving at 141.9 meters per second.

b) How fast was he moving in miles per hour?

[tex] v = \frac{d}{t} = \frac{1000 m}{7.045 s} = 141.9 m/s*\frac{3600 s}{1 h}*\frac{1 mile}{1609.34 m} = 317.4 miles/h [/tex]      

Therefore, the jet ski is moving at 317.4 miles per hour.

Explanation:

The acceleration on an object due to the gravity of any massive body is represented by g (small g). The force of attraction between any two unit masses separated by unit distance is called universal gravitational constant denoted by G(capital g). The relation between G and g is not proportional. That means they are independent entities.

G and g

In physics, G and g can be related mathematically as –

\(g=\frac{GM}{R^{2}}\)

Where,

1=g is the acceleration due to the gravity of any massive body measured in m/s2.

2=G is the universal gravitational constant measured in Nm2/kg2.

3=R is the radius of the massive body measured in km.

4=M is the mass of the massive body measured in Kg.

Answer:

200 mph.

Explanation:

If a NASCAR driver travels 600 miles in 3 hours, the way to calculate the speed at which the car is driving comes from dividing the distance factor by the time factor.

Thus, we must divide 600 by 3 (600/3), which gives 200 as result. Thus, if in 3 hours he travels 600 miles, in one hour he will travel 200 miles, which means that his average speed is 200 mph.

Answer:

The car's initial velocity is 195.96 m/s

Explanation:

Given;

the length of the mark, x = 9.6 km = 9600 m

acceleration of the car, a = -2 m/s²

Apply the kinematic equation below

v² = u² + 2ax

where;

v is the final velocity = 0

u is the initial velocity

simplify the equation and you will obtain;

0 = u² + 2ax

0 = u² + 2(-2)(9600)

0 = u² - 38400

u² = 38400

u = √38400

u = 195.96 m/s

Therefore, the car's initial velocity is 195.96 m/s

Answer:

The object moves 6 m in every second.

Explanation:

When we say something is constant, we simply means that it does not change with time i.e it the same through out irrespective of time.

Now, let us answer the question given above.

An object moving at a constant speed of 6 m/s. Has the following characteristics:

1. The object moves 6 m in every second.

2. The object is not accelerating since it has a constant speed. Therefore, the acceleration of the object is zero.

3. The object is moving as it covers a distance of 6 m in every second.

4. The speed remains the same since the speed of object is constant.

Thus, the right answer to question is: The object moves 6 m in every second.

Answer:

q₁ / q₂ = 4

Explanation:

In this exercise we must use Coulomb's law

         F = k q₁q₂ / r²

For this case the electric force is

        F = k q₁ Q / r₁²

indicate that another particle q₂ has the same force on Q, but for r₂ = r₁ /2

        F = k q₂ Q / r₂²

we equate the two equations

           q₁Q / r₁² = q₂ Q / r₂²

we substitute r₂

        q₁Q / r₁² = q₂ Q / (r₁/2)²

        q₁ = q₂ 4

the relationship between the two charges is

         q₁ / q₂ = 4

Answer:

All investigations share steps of the scientific method, such as asking a question, conducting research, or analyzing data. The differences between investigations are usually related to what's being examined and the order of the steps followed.

In a criminal investigation, facts are collected about a crime that has already happened. While there are individual tests that can be done on certain types of evidence, there isn't an experiment to test every part of a crime. It can also be difficult to control all factors in a crime scene in order to test one variable at a time. Usually, there are so many variables and missing facts in a crime that a hypothesis and conclusion are hard to determine.

Explanation:

hope it helps <3

All types of investigation involve the steps of the scientific method, such as asking questions, researching, analyzing data, etc.

The research methods and techniques that can be used in order to develop hypotheses, conduct experiments, analyze data, and draw conclusions are called scientific investigations.

The evidence does not give enough solutions but it can lead to new issues for investigation. The methods that can be used by scientists to do scientific investigations involve scientific methods. The steps utilized by scientists to conduct the scientific investigation include:

Scientific investigation starts with an observation. After observing unusual we commonly question ourselves.

A hypothesis can be described as the possible answer to any scientific question. The hypothesis is logical still it can be falsifiable. The results of the test whether the evidence agrees with the prediction and supports the hypothesis or not to create a conclusion.

Answer:

13.33 seconds

Explanation:

At maximum height, the equation of motion becomes:

v = u + at

Since the object was thrown vertically, the initial velocity (u) is zero and the acceleration (a) becomes the acceleration due to gravity (10 m/s2). The equation becomes:

v = at

v = 480 km/hr = 133.333 m/s

    10t = 133.333

       t = 133.333/10

           t = 13.33 seconds.

The time for the ball thrown vertically with a velocity of 480 km/hr to reach the maximum height is 13.33 seconds.

The car's average acceleration is

a (ave) = (30 m/s - 40 m/s)/(5 s) = -2 m/s^2

(That is, divide the change in velocity by the time it takes for the change to take place.)

If acceleration is constant, then it is equal to the average acceleration.

Answer:

Total height (s) = 176.4 m

Explanation:

Given:

Initial velocity (u) = 0 m/s

Time taken (t) = 6 sec

Acceleration due to gravity = 9.8 m/s²

Find:

Total height (s)

Computation:

s = ut + [1/2]gt²

s = (0)(6) + [1/2][9.8][6²]

s = 176.4 m

Total height (s) = 176.4 m

Answer:

33 hours or equivalently: 1980 minutes

Explanation:

Use the formula for movement under constant velocity, as the velocity equal the distance traveled divided by the time it took, and solve for the unknown time (t):

[tex]v=\frac{distance}{t} \\t=\frac{distance}{v} \\t=\frac{8.25\,\,km}{0.5 \,\,km/h} \\t = 33 \,\,h[/tex]

which can also be given in minutes as : 33 x 60 = 1980 minutes

Explanation:

Using kinematics,

t = 4s

u = 0m/s

a = 9.8m/s^2

Therefore v = u + at = 0 + (4)(9.8) = 39.2m/s.

Answer:

Acceleration and the distance traveled are 0.9 m/s² and 4.05 m

Explanation:

Given that,

Initail speed, u = 0

Final speed, v = 2.7 m/s

Time, t = 3 s

To find,

The acceleration and distance traveled.

Solution,

Acceleration is change in speed per unit time

[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{2.7-0}{3}\\\\a=0.9\ m/s^2[/tex]

Let s is the distance,

[tex]d=ut+\dfrac{1}{2}at^2\\\\\because u=0\\\\d=0+\dfrac{1}{2}\times 0.9\times 3^2\\\\d=4.05\ m[/tex]

So, acceleration and the distance traveled are 0.9 m/s² and 4.05 m
