Answer:
The car travel 2.52 m
Explanation:
This problem gives us the time and speed of the car with the echolocation system, and they ask us for the distance traveled, we can use the report motion equation.
Let's start by calculating the relative speed of the two cars, which in this case is the initial mass because the second vehicle is at rest.
v = d / t
d = v t
d = 14 0.18
d = 2.52 m
The car travel 2.52m
Answer: The heating of the Earth's surface and atmosphere by the sun drives convection within the atmosphere and ocean. This convection produces winds and ocean currents. The greater the pressure differences between a low-pressure area and a high-pressure area, the stronger the winds.
Explanation:
The escape velocity on Venus is 9761 m/s
Explanation:
The escape velocity from a planet is the speed that an object on the surface of that planet must have in order to completely escape the gravitational field of the planet.
Mathematically, it is calculated as
where
G is the gravitational constant
M is the mass of the planet
R is the radius of the planet
For Venus, we have:
is the mass
is the radius
Substituting, we find the escape velocity on Venus:

Among the choices the one that is correct about relationship between the readings is letter D which is RC RD
Answer:
45500 J
Explanation:
Pressure, P =350 kPa = 350 x 1000 Pa
V1 = 0.02 m^3
V2 = 0.15 m^3
Work done by the piston
W = Pressure x increase in volume
W = P x (V2 - V1)
W = 350 x 1000 (0.15 - 0.02)
W = 45500 J
Thus, the work done is 45500 J.
