Answer: n the laboratory, the life time of a particle moving with speed 2.8 x 10^10 cm\s is found to be 2.5 x 10^-7. Calculate the proper life of the ...
Explanation:
Answer:
F = 0 [N]
Explanation:
To solve this problem we must perform a summation of forces in the direction of the vertical axis. Where the positive force is that of the tension of the upward force, while the force exerted by the weight is directed downward with a negative sign.
ΣF = 0
15 - 15 + F = 0
F = 0 [N]
The ampere (symbol: A) is the SI base unit of electric current equal to one coulomb per second.
The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross section, and placed 1 meter apart in vacuum, would produce between these conductors a force equal to 2 times 10–7 newton per meter of length.
Electric current is the time rate of change or displacement of electric charge.
One ampere represents the rate of 1 coulomb of charge per second.
The ampere is defined first (it is a base unit, along with the meter, the second, and the kilogram), without reference to the quantity of charge.
The unit of charge, the coulomb, is defined to be the amount of charge displaced by a one ampere current in the time of one second.

Answer:
<h2>8.78 Amps</h2>
Explanation:
Given data:
power rating of the heater P= 1010 W
voltage of the heater V= 115 volts
current taken by the heater I= ?
We can apply the power formula to solve for the current in the heater
i.e P= IV
Making I the current subject of formula we have
I= P/V
Substituting our given data into the expression for I we have
I=1010/115= 8.78 A
<h2 /><h2><em>Hence the current when the unit/heater is operating is 8.78 Amp</em></h2>
