The correct answer should be a
Answer:
31.68 meters per second.
Explanation:
Speed is equals to Distance divided by Time, so, this means that speed is inversely proportional to time and directly proportional to distance.
Here, Distance is given which is 274 meters.
Time taken to cover the given distance is 8.65 seconds.
So, by putting the values of distance and time in the formula of speed we will get the top speed of Cheetah which is 31.68 meters per second.
Answer:
Radius = 3.96m
Explanation:
In a cyclotron motion, the radius of a charged particle path in a magnetic feild is given by:
r = mv/qB
Where r = radius
m = mass of particle= 9.1×10^-31kg
q = charged electron = 1.6×10^-19C
B = magnetic feid = 7.65×10^6T
V = velocity = 7.65×10^6
r = (9.1×10^-31)×(7.65×10^6) / (1.6×10^-19)(1.10 ×10^-5)
r = (6.9615×10^-24)/(1.76 ×10^-24)
r = 3.96m
The neutron. As a neutron breaks apart the nucleus of a uranium atom, it causes a chain reaction releasing more neutrons. When we control this reaction we can harness the energy and produce nuclear power. When the reaction is left unchecked you get a immensely powerful release of energy, an atomic bomb.
