Answer:
A sloping surface separating air masses that differ in temperature and moisture content is called a front.
You must first convert minutes to seconds so 10*60=600
Then multiply the number of seconds by the speed so 600*2=1200 m
Answer: The velocity with which the sand throw is 24.2 m/s.
Explanation:
Explanation:
acceleration due to gravity, a = 3.9 m/s2
height, h = 75 m
final velocity, v = 0
Let the initial velocity at the time of throw is u.
Use third equation of motion
The velocity with which the sand throw is 24.2 m/s.
<span>Energy is transferred from one object to another
when a reaction takes place. Energy comes in many forms and can be
transferred from one object to another as heat, light, or motion, to
name a few. For the blue ball to move to the position of the green ball,
energy must be given to the blue ball. This energy would be in the form
of motion, with the person lifting the blue ball to a higher level.
This form of energy is called kinetic energy.</span>
Answer:
The minimum coefficient of static friction between the road and the car's tires is 0.816
Option "C"
Explanation:
Given;
velocity of the car, v = 40.0 m/s
radius of horizontal curve, r = 200 m
For a minimum coefficient of static friction between the road and the car's tires that will allow the car to travel at the given speed without sliding, centripetal force must equal frictional force.
where;
μ is the minimum coefficient of static friction
Thus, the minimum coefficient of static friction between the road and the car's tires is 0.816
Option "C"
