Answer:
0.88
Explanation:
velocity (v) = 22 m/s
radius (r) = 56 m
acceleration due to gravity (g) = 9.8 m/s^{2}
What minimum coefficient of static friction between the tires and road is necessary for the car to round the curve without slipping?
for the car to successfully go round the curve, the frictional force must be equal to or greater than the normal force, therefore
Normal force = frictional force
ma = μmg
where
- μ = coefficient of friction
- g = acceleration due to gravity
- a = = = 8.6
- putting in all required values the equation now becomes
8.6m = μm x 9.8
8.6 = 9.8 x μ
μ = 8.6/9.8 = 0.88
Answer:
<em>P = 1500 Watt</em>
Explanation:
<u>Mechanical Work and Power
</u>
Mechanical work is the amount of energy transferred by a force.
Being F the magnitude of the force vector and s the distance, the work is calculated as:
W=F.s
Power is the amount of energy transferred or converted per unit of time. In the SI, the unit of power is the watt, equal to one joule per second.
The power can be calculated as:
Where W is the work and t is the time.
The force to be considered is the weight of the mass of m=100 kg, :
F = 100 * 10 = 1000 N
The distance is s=3 m, thus the work done by the weight lifter is:
W = 1000 N * 3 m
W = 3000 J
Finally, the power is:
P = 1500 Watt
Answer:
A tornado can, surprisingly, cause a supercell, so the answer would be C.) tornado
Explanation:
When cold, dry, and polar air meet warm, moist tropical air, the atmosphere becomes unstable causing a supercell.
Final Answer:
C.) tornado
