Hello jamaicandoll!
What is the force on a body if the mass of the body is 2300g? (acceleration due to gravity = - 9.8m/s²) .
Given,
- Mass (m) = 2300 g = 2.3 kg
- Acceleration (a) = -9.8 m/s²
- Force (F) = ?
We know that, force = mass × acceleration.
So,
F = ma
F = 2.3 × -9.8
F =

Answer:
E_total = 3 N / A
Explanation:
The electric field is a vector magnitude so when adding we must use vectors, in this case as the initial field E = 4N / c goes towards the axis axis and the field created by the fixed charge (E1) is also on the axis x we can add in scalar form.
E_total = E + E₁
the expression for the field of a point charge is
E₁ = k q₁ / r²
for the point x = 2m, they do not say that the total field is zero, so the charge q1 must be negative
E_total = E -k q₁ / r₂
we substitute
0 = E - k q₁ / r²
q₁ =
let's calculate
q₁ =
q₁ = 1.78 10⁻⁹ C
now we can calculate the field for position x = 4 m
E_total = 4 - 9 10⁹ 1.78 10⁻⁹ / 4²2
E_total = 3 N / A
Answer:
The number of atoms is
Explanation:
From the question we are told that
The mass of coin is
Number of atom in one mole =
Molar mass of nickel
Now the relation to obtain the number of atom in the nickel coin is
