Answer:
T=7.4 N hence T<30 N
Explanation:
The figure is likely to be similar to the one attached. Writing the equation for forces we have
F-T=Fa/g where F is the force, T is tension, a is acceleration and g is acceleration due to gravity. Substituting the figures we have the first equation as
30 N - T = (30/9.81)a
Also, we know that T=F*a/g and substituting 10N for F we obtain the second equation as
T = (10/9.81)a
Adding the first and second equations we obtain
30 = 4.077471967
a Hence
and T=a hence
T is approximately 7.4 N

Answer:
Electric field on proton
Explanation:
Given that
We know that
Charge on proton
We know that
Force = Electric field x Charge
F= E x q
Electric field on proton
Power = (voltage) x (current)
100w = 220v x current
Current = 100w / 220v = <u>0.455 Ampere</u> (rounded)
