Circumference of the tire = (2 pi) x (radius)
= (2 pi) x (0.62 meter)
= 3.9 meters
If the tire never slips or skids, then the speed of the vehicle is
speed = (distance) / (time to cover the distance)
= (5 x 3.9 meters) / 1 second
= 19.48 meters/second .
(about 43.6 miles per hour) .
We can't say anything about the vehicle's velocity, because we have
no information about the direction in which it's heading.
Answer:
B. 8,437.5 J
Explanation:
<u>Given the following data;</u>
Height = 400m
Mass = 75kg
Velocity = 15m/s
Time = 10 secs
To find the kinetic energy of the skier?
Kinetic energy can be defined as an energy possessed by an object or body due to its motion.
Mathematically, kinetic energy is given by the formula;
<em>Where;</em>
- <em>K.E represents kinetic energy measured in Joules. </em>
- <em>M represents mass measured in kilograms. </em>
- <em>V represents velocity measured in metres per seconds square. </em>
<em>Substituting into the equation, we have;</em>
K.E = 8,437.5 Joules.
Answer:
10 Hz
Explanation:
Frequency of wave is given by
f= v / lambda
f= 30 / 3
f= 10

The statement would be False. T<span>he potential energy of a membrane potential comes solely from the difference in electrical charge across the membrane. In addition to that, membrane potential actually regulates the potential difference of nerve cells across the membrane estimated at 70 mV.</span>
