Answer:
Relativistic energy is conserved as long as we define it to include the possibility of mass changing to energy. Total Energy is defined as: E = γmc2, where γ=1√1−v2c2 γ = 1 1 − v 2 c 2 . Rest energy is E0 = mc2, meaning that mass is a form of energy. If energy is stored in an object, its mass increases.
Step-by-step explanation:
Answer:
Energy can either be potential energy or kinetic energy, but mechanical energy
Mechanical energy = Potential energy + Kinetic energy
[tex]potential \: energy = mgh \\ kinetic \: energy = \frac{1}{2}m {v}^{2} \\ mechanical \: energy = mgh + \frac{1}{2} m {v}^{2} \\ = \frac{1}{2} m(2gh + m {v}^{2} )[/tex]
Then for Eistein mass energy relation
E = mc²
c is speed of light

WILL GIVE BRAINLIEST TO YOU!!! I have two equations, Equation A and Equation B. When I try to solve the system, I get no solution. What can you tell me about the graphs of Equation A and Equation B?
I have two more equations, Equation C and Equation D. When I solve this system, I get infinitely many solutions. What can you tell me about the graphs of Equation C and Equation D?
For the 1st one, the equations never intersect. There is only 1 case where the lines never intersect and that is when they are parallel. So the 1st one is that they are parallel. A and B are parallel when graphed.
For the 2nd one, the lines are always intersecting. This means that C and D are the same line when graphed.
Answer:
see explanation
Step-by-step explanation:
The solution of equations given graphically is at the point of intersection of the 2 lines.
No solution indicates that there is no point of intersection, thus the graph of A and B are parallel lines which never intersect.
B
Infinitely many solutions indicates that the graph of C and D lie on the same line.
What is the slope of any line parallel to the y-axis in the
(x, y) coordinate plane?
F. -1
G. O
H. 1
J. Undefined
K. Cannot be determined from the given information
Answer:
A line parallel to the y-axis in the (x, y) coordinate plane is undefined.
Hence, option J is correct.Step-by-step explanation:
We know that the slope of a vertical line on a coordinate plane is undefined.
We also know that a line parallel to the y-axis is basically a vertical line.
Therefore, a line parallel to the y-axis in the (x, y) coordinate plane is undefined.
Hence, option J is correct.EXAMPLE
For example, considering the two points of a line
(x₁, y₁) = (1, 3)
(x₂, y₂) = (1, 5)
Determining the slope between (1, 3) and (1, 5)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [5 - 3] / [1 - 1]
= 2/0
= ∞ or undefined
Thus, the slope of the line = m = undefined
Thus, the equation of a line parallel to y-axis passing through the points (1, 3) and (1, 5) will be:

. Laura and Alicia both exercise 5 days a week. Laura exercises for 30 minutes each day. Alicia exercises for 45 minutes each day. How much longer does Alicia exercise than Laura each week?. Laura and Alicia both exercise 5 days a week. Laura exercises for 30 minutes each day. Alicia exercises for 45 minutes each day. How much longer does Alicia exercise than Laura each week?
Answer: 1 hour 15 minutes
Step-by-step explanation:
From the question, we are informed that Laura and Alicia both exercise 5 days a week and that Laura exercises for 30 minutes each day. For the 5 days, she'll exercise for:
= 5 × 30 minutes
= 150 minutes
= 2 hours 30 minutes
Alicia exercises for 45 minutes each day. Fir the 5 days, she'll exercise for:
= 5 × 45 minutes
= 225 minutes
= 3 hours 45 minutes
We then calculate the difference in their exercise per week which will be:
= 3 hours 45 minutes - 2 hours 30 minutes
= 1 hour 15 minutes

Marsha deposited $5,500 into a savings account 2 years ago. The simple interest rate is 4%. How
much money did Marsha earn in interest?
Substitute the values into the equation.
The earned $440 in interest depositing $5500 for 2 years at 4% rate of interest.
What is simple interest?
We know simple interest (SI) is given by SI = (p×r×t)/100, where
p = principle, r = rate in percentage, and t = time in years.
Simple interest is often a predetermined percentage of the principle amount borrowed or lent paid or received over a specific time period.
Given, Marsha deposited $5,500 into a savings account 2 years ago at 4% simple interest.
So, p = 5500, r = 4 and t = 2.
Therefore,
SI = (5500×4×2)/100.
SI = 440.
So, Marsha earned $440 in interest.

Answer:
what have we nothing to go buy
Answer:
y=(-4/3)x+2
Step-by-step explanation:
we have two points (3,-2) and (0,2) given from the statement
the equation of the lines is:
y=mx+b
m=slope
m=(y2-y1)/(x2-x1)
m=(2-(-2))/(0-3)
so we have the slope is
m=4/-3 =-4/3 =-1.3333
we need to find "b"
using the point (0,2)
we have :
2=m*0+b
2=b
finally, we have
the answer is y=(-4/3)x+2

Answer:
15.2 meters
Step-by-step explanation:
50 ÷ 3.3 = 15.15
1 meter= 3.3 feet, so when BASKETBALL The standard width of a high school basketball court is 50 feet. then width is 15.15 meters of the basketball court in meters.
What is 1 meter in feets?1 meter= 3.3 feet
Given width of high school basketball is 50 feet and1 meter = 3.3 feet.,
We need to find the value of 1 feet.
1 feet= 1meter/3.3
1 feet=0.3030
Now to calculate 50 feet , we need to multiply 50 with 1 feet.
50*0.3030=15.15Meters
Therefore 15.15 meters is the width of the basketball court in meters.

Answer:
180 degrees since only two opposite sides are congruent in a rect, which would require you to flip it 180 degrees for it to map onto itself
Answer: 180 degrees
Imagine you had a long and flat rectangle. If we spin it around the center, we can rotate it 180 degrees so it lines up with its original image. The before and after is the same. We say it has rotational symmetry, and the angle of rotation is 180 degrees. This is the smallest rotational angle possible for rectangles that aren't squares.
