The characteristic is that it can change back to a liquid or gas by being heated
Answer:
While weight training will improve muscle strength and mass, the potential of a body to develop muscle is limited in part by genetic factors that are out of an individual's control.
Explanation:
Answer:
21.7 m/s
Explanation:
To solve this problem, we have to write the equations of motion along the two directions: horizontal and vertical.
Horizontal direction:
Vertical direction:
where:
N is the normal reaction on the car
is the banking angle of the road
is the coefficient of friction of concrete
m is the mass of the car
v is the speed of the car
r = 40 m is the radius of the curve
is the acceleration due to gravity
Combining the two equations together, we can find the maximum speed allowed for the car:
And substituting the data we have, we find:
Answer:
θ = 51.21°
Explanation:
Vh= 193.6 km/h
Va= 141.7 km/hr
Relative velocity ,Vr= 193.6 - 141.7 = 51.9 km/hr
Time taken to cover 71.3 m
t= 3.81 s
t= 0.00105 hr
So the horizontal distance x
x= Vr .t
x= 51.9 x 0.00105 km
x=0.0549 m
x= 54.96 m
Lets take angle is θ
tan θ = h/x
tan θ = 71.3/54.96
θ = 51.21°
Answer: 0.22
