The kinetic energy of an object is given by the formula E = mv2. If m is in kg and v is in m/s,
then E is in joules. What is the kinetic energy of an electron (mass = 9.1 x 10-31kg) travelling at a
fifth of the speed of light (speed of light, c = 3 x 108m/s)?

Answers

Answer:

9.553×10^-26

Step-by-step explanation:

m= 9.1 ×10 ^-31

v = 3 × 108

= ( 9 .1 × 10 ^- 31) × ( 3 × 108 ) ^2

= 9 .552816 × 10 ^ -26

%
of the
40
students in her class could not give the correct answer.

What is the number of students who answered correctly?

Answers

Answer:

Step-by-step explanation:

find 10% = 4

quadruple it = 16

half 10% = 2

half it again = 1

2.5% = 1

40% = 16

1 + 16 = 17

take 17 off of 40 = 23

100% - 42.5% = 57.5%
57.5% of the 40 students answered correctly.
57.5% of 40 = 0.575 × 40 = 23 students

The equation of the proportional relationship represented by the table and the graph is: y = 2x.

What is a Proportional Relationship?

If m is the slope or unit rate, a proportional relationship between two variables, x and y, can be represented with an equation as, y = mx.

Let's find the equation that represents the relationship represented by the graph and the table. Let's use the graph.

m = y/x

Using the point, (2, 4),

m = 4/2 = 2

Substitute m = 2 into y = mx

y = 2x

Therefore, the equation of the proportional relationship represented by the table and the graph is: y = 2x.

Answers

Answer:

Yes it is true. Sum of two integers is always an integer

Step-by-step explanation:

Rule: The sum of any integer and its opposite is equal to zero. Summary: Adding two positive integers always yields a positive sum; adding two negative integers always yields a negative sum. To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values.

Answer:

[tex]sin 40 = \frac{x}{11}[/tex]

Step-by-step explanation:

[tex]sine = \frac{opposite}{hypotenuse}[/tex]

Side x is the opposite, since it is opposite the angle you are solving for.

Side y is the adjacent, since it is next to the angle you are solving for.

The side measuring 11 is the hypotenuse, since it is across from the right angle.

use the change flip method due to divide

Answer:

See step-by-step explanation.

Step-by-step explanation:

When dividing a fraction it is not actually dividing, it is more multiplying.

Our sum looks like this:

3/5 ÷ 1/3

The method here is to flip the second fraction and change the divide sign into a multiplication sign. Here is what is looks like step-by-step.

3/5 ÷ 1/3

3/5 ÷ 3/1

3/5 × 3/1

Now we can finish the sum off by multiplying across.

3 × 3 = 9

5 × 1 = 5

9/5, this is a top-heavy fraction.

If we want it as a mixed fraction then here it is:

1 4/5 (that is one and four fifths).
