Answer:
Net force ( F ) = 208 N.
Speed of car ( v ) = 68.58 m/s.
Explanation:-
The radius ( r ) = 480 m.
Mass of passenger ( m ) = 65 kg.
Horizontal force (
) = 208 N.
Vertical force (
) = 637 N.
Net vertical component of force (
) = m*g - 637 = 65 * 9.8 - 637 = 0 N.
a ) magnitude of net force .
= 208 N.
b) The speed of car.
where v is the velocity.

v² = 4704
v = 68.58 m/s.
1. Fertile soil.
2. Ore deposits.
3. Fossil fuels
Answer:
Conservation
Explanation:
She has observation conservation because If the temperature of the liquids stays constant and the container is insulated and not heat or cool the liquid much would not change the density of the liquid very much so that it's original volume could remain constant.
The interesting thing is not that the child assumes the taller glass holds more liquid but that they fail to understand conservation: the fact that the water from one glass is going to be the same amount after being poured into any other container. It's as if they did not realize the water came from the same glass.
Explanation:
It is given that, the water from a fire hose follows a path described by equation :
........(1)
The x component of constant velocity, 
We need to find the resultant velocity at the point (2,3).
Let
and 
Differentiating equation (1) wrt t as,



When x = 2 and 
So,


Resultant velocity, 

v = 6.4 m/s
So, the resultant velocity at point (2,3) is 6.4 m/s. Hence, this is the required solution.
Answer : B - real
Explanation : 1. you can see the image the way it is as in its no in a mirror.
2. The image will not be inverted
But it could be magnified too tbh. But I would go for real
