No Solution:
4x+10y = 40
2x + 5y = 40
2x - 8y=17
x - 4y = 7
One Solution:
2y - X= 12
2y - 2x =10
x + 10y =50
2x + 10y =90
Infinitely Many Solutions:
x + 2y = 1
3x + 6y= 3
2y - 3x = 5
2/5y -3/5x =1

Answer:
7056 kJ
Explanation:
Given that,
Mass of a ship roller coaster is 36,000 kg.
It reaches a height of 20 m off the ground
We need to find the gravitational potential energy does it have. The formula for the gravitational potential energy ios given by :
E = mgh
g is acceleration due to gravity
E = 36,000 kg × 9.8 m/s² × 20 m
= 7056000 J
or
E = 7056 kJ
So, it will have 7056 kJ of gravitational potential energy.

Answer:
Option C
Explanation:
Given
Pressure = Force /Area
For any gas sample, force is defined as basically the force exerted by the gas molecules when they strike the surface (with in which they are contained) and bounce back.
Hence, Option C is the correct
The wavelength of a wave (λ) is given by λ

where c is the wave speed and f is the frequency
