To find the mass, with only the weight:

⇒ must consider the relationship between the mass and weight

⇒ (in other words) we must find the equation that has both the

mass and weight

Based on our physics knowledge, we know:

$Weight=mass*gravitational_. acceleration$

Weight: 147N
Gravitational Acceleration: 9.8 m/s²

Now let's plug in the values, and solve:

$147N = mass*9.8_.m/s^2\\mass = 15_.kg$

Answer: 15 kg

Hope that helps!

*as a note, if you use the gravitational acceleration as 10m/s², then the answer would be 14.7 kg

If a force of 25 N is applied to an object with a mass of 8 kg, the object will accelerate at

.
the formula for acceleration is as follows:
force/mass = acceleration
-
so 25/8 = 3.13

A manufacturer claims that a carpet will not generate more than 5.8 kV of static electricity What magnitude of charge would have

DiKsa [7]

Answer:

4.4×10⁻⁷ Coulomb

Explanation:

V = Voltage = 5.8 kV

d = Potential distance = 2.8 mm = 0.0028 m

A = Area = 0.3×0.08 = 0.024 m²

ε₀ = permittivity constant in a Vacuum= 8.85×10⁻¹² F/m

$\frac{Q}{V}=\frac{A\epsilon_0}{d}\\\Rightarrow \Q=V\frac{A\epsilon_0}{d}\\\Rightarrow Q=5.8\times 10^3\frac{0.024\times 8.85\times 10^{-12}}{0.0028}\\\Rightarrow Q=4.4\times 10^{-7}\ C$

Magnitude of charge transferred between a carpet and a shoe is 4.4×10⁻⁷ Coulomb.

Answer:

D) 735 J(oules)

Explanation:

Work is defined as force * distance

Force is defined as mass * acceleration

Given a mass of 15 kg and a gravitational acceleration of 9.8 m/s² since the box is being lifted up, the force being applied to the box is 15 kg * 9.8 m/s² = 147 N

Since the distance is 5 meters, the work done is 147 N * 5 m = 735 N/m = 735 J, making D the correct answer.
