Answer:,20,15.7
Explanation:
Frequency is defined as the number of revolutions made the object in unit time.
Given that it takes minutes revolutions.
So, revolutions can be completed in minute.
So, revolutions can be completed in a second.
So,frequency is
Period of a object is the inverse of frequency.
Inverse of frequency
So,period is .
Speed of car is the given by the ratio of distance covered in one revolution to the time period.
Distance travelled in one period is where is the diameter.
Given that
So,distance travelled in one revolution
Time period is .
Speed is
Final Answer:
65.25 J is the kinetic energy that the ball has.
Explanation:
M = 145g
(Reminder: kg must be used in this formula, thus we need to convert 145g to kg)
M = 145g x 1kg/1000g
(cross out g, then multiply 145 to 1kg)
M = 145kg/1000 = 0.145kg
M = 0.145 kg
V = 30.00 m/s
Solution:
KE = 1/2mv^2
KE = 1/2(0.145kg)(30.00m/s)^2
(Square first the velocity)
KE = 1/2(0.145kg)(900.00m^2/s^2)
KE = 1/2(130.5 kg*m^2/s^2)
KE = 65.25 kg*m^2/s^2
(Reminder: 1 kg*m^2/s^2 = 1 J)
KE = 65.25 J
Final Answer:
65.25 J is the kinetic energy that the ball has.
Answer:
The hydrosphere, the sphere of influence that deals with water in its various forms (some separate out ice and call that the cryosphere), provides the biosphere with a much needed component....water. Life would not exist as we know it without water. It places in important role for all organisms, alongside playing an important role in various earth processes.
Explanation:
Answer:
The greenhouse effect is a natural warming process of the earth. ... This outgoing longwave radiation is partially trapped by greenhouse gases such as carbon dioxide, methane and water vapour which then radiate the energy in all directions, warming the earth's surface and atmosphere.
