The box is moving in the direction of Eduardo with a force of 300N since he is pulling 300N stronger than Clara.
Answer:
2.2kg
Explanation:
kilograms is a measurement of mass so the answer is 2.2kg
Answer:
The correct question is:
"Find the energy each gains"
The energy gained by a charged particle accelerated through a potential difference is given by
where
q is the charge of the particle
is the potential difference
For a proton,
And since 
The energy gained by the proton is
For an alpha particle,
Therefore, the energy gained is
Finally, for a singly ionized helium nucleus (a helium nucleus that has lost one electron)
So the energy gained is the same as the proton:
We use the formula,
.
Here, v is velocity and its value given 26 mi/h ( in m/s, 
) and d is distance and its value is given 80 m.
Substituting these values in above formula we get,
Thus, the time delay between green lights on successive blocks to keep the traffic moving continuously is 6.88 s
1333.3 is the frequency in the hertz of a signal that repeats 80,000 times within one minute. 0.00075 is its period.
The frequency of a repeated event is its number of instances per unit of time. In some cases, it is also referred to as temporal frequency or ordinary frequency to underline differences with spatial and angular frequencies, respectively.
The length of time it takes for a particle in a medium to complete one full vibrational cycle is the period of a wave. Being a time, a period is measured in time units like seconds, hours, days, or years. The Earth's orbit around the Sun has a duration of around 365 days, and one cycle of the Earth lasts 365 days.
frequency = cycle /second
frequency = 80000 / 60
frequency = 1333.3 hertz
Period = 1 / frequency
Period = 1 / 1,333.3
Period = 0.00075
