1. F=ma
Here we have an acceleration = 2.3 and a mass = 14
So...
F = (14)(2.3)
F = 32.2 N
2. F = ma
Here we have an acceleration = 6.4 and a force = 1473
Rearrange your equation for m
F/a = m
1473 / 6.4 = m
m = 230.16 kg
3. F = ma
Here we have a force = 94 and a mass = 45
Rearrange for acceleration
F/m = a
94 / 45 = a
a = 2.09 m/s^2
Answer: Density is defined as the mass per volume of a substance. Thus, air density is defined as the mass of air per unit volume. Using... Air pressure, or atmospheric pressure, is defined as the weight of air in Earth's (or another planet's) atmosphere.
Explanation:
Answer:
the magnitude and direction of the uniform electric field is 1846.38 N/C and UPWARD respectively
Explanation:
Given the data in the question;
mass m = 1.30 g = 1.30 × 10⁻³ kg
Charge q = +6.90 µC = 6.90 × 10⁻⁶ C
we know that; g = 9.8 m/s
assuming gravity and the electrostatic force are the only forces exerted on the particle, hence the relation is;
F = mg and F = Eq
so
mg = Eq
make E subject of formula
E = mg / q
so we substitute
E = [ (1.30 × 10⁻³) × 9.8 ] / 6.90 × 10⁻⁶
E = 0.01274 / 6.90 × 10⁻⁶
E = 1846.38 N/C
Since the charge is positive ( + ), { direction is Upward }
Therefore, the magnitude and direction of the uniform electric field is 1846.38 N/C and UPWARD respectively
