Answer:3,45 x 10^9 N
Explanation: We have considered the total charge for each coin , this is the total atoms x 29 electrons for cooper and multiplier by electron charge, the total charge for each coin is 0,464 C
Finally we use the Coulomb law,
F=k Q/ (r)^2
Answer:
Part of the question is missing but here is the equation for the function;
Consider the equation v = (1/3)zxt2. The dimensions of the variables v, x, and t are [L/T], [L], and [T] respectively.
Answer = The dimension for z = 1/T3 i.e 1/ T - raised to power 3
Explanation:
What is applied is the principle of dimensional homogenuity
From the equation V = (1/3)zxt2.
- V has a dimension of [L/T]
- t has a dimension of [T]
- from the equation, make z the subject of the relation
- z = v/xt2 where 1/3 is treated as a constant
- Substituting into the equation for z
- z = L/T / L x T2
- the dimension for z = 1/T3 i.e 1/ T - raised to power 3
Answer: Earth scientists have theorized that the Earth's core is responsible for the planet's magnetic field as well as plate tectonics.
Explanation:
Answer:
v = 2000m/60s; v = 33.33 m/s (plus, in velocity direction is needed in answer, if given)
Explanation:
velocity = distance/time
There are too many batteries in the circuit, which increased the emf of the circuit and in turn increased the current in the circuit.
<h3>
Current in the circuit</h3>
The current in the circuit is determined by applying Ohms law as shown below;
V = IR
where;
- I is the current
- V is the voltage
- R is the resistance
I = V/R
At a constant resistance of the circuit, the current in a circuit will increase when the emf of the circuit increases.
Thus, we can conclude that, there are too many batteries in the circuit, which increased the emf of the circuit and in turn increased the current in the circuit.
