Answer:
The direction of the net force is in the same direction as the acceleration. So for an object moving in a circle, there must be an inward force acting upon it in order to cause its inward acceleration. This is sometimes referred to as the centripetal force requirement.
Explanation:
d = M/V, where d is density, M is mass, and V is volume, is the formula for density. Grams per cubic centimeter are a typical unit of measurement for density.
To fill the graduated cylinder to the 2.0 mL mark, add water. The water makes a curve if you see the graduated cylinder from the side. Make sure the 2.0 mL level is at the bottom of the curve. Calculate the graduated cylinder's mass and the water's mass in milliliters using the gram scale. In the table, note the mass. Subtract the graduated cylinder's mass to determine the mass of 2.0 mL of water. To find and note the mass of 4.0 mL of water, repeat this procedure.

One of the handy formulas for electrical power is
Power = (Voltage)² / (Resistance)
Since the voltage is squared, if you double the voltage and
the resistance doesn't change, the power will increase by
the factor of (2²), which is 4 times the original power.
Answer:
A = 70cm³
B= 805 grams
Explanation:
(a) V = L×B×H
= 7cm × 5cm × 2cm
= 35cm × 2cm
= 70cm³
(b) Mass= volume × Density
= 70cm³ × 11.5g/cm³
=805 grams

Answer:
Explanation:
Work required = q x V
where q is charge on electron and V is potential difference
= 1.6 x 10⁻¹⁹ x 12
= 19.2 x 10⁻¹⁹ J
