[r] =6
Solve for r by simplifying both sides of the equation, then isolating the variable.

Hey give us m = 9.0 g = 9.0 x 10-3 kg, and a = 10,000 "g's" = 98000 m/s/s so:F = ma = (9.0 x 10-3 kg)(98000 m/s/s) = 882 N = 880 N
Answer:
speed and acceleration
Explanation:
speed is a scalar quantity
acceleration is a vector quantity
Answer:
The final velocity of the vehicle is 10.39 m/s.
Explanation:
Given;
acceleration of the vehicle, a = 2.7 m/s²
distance moved by the vehicle, d = 20 m
The final velocity of the vehicle is calculated using the following kinematic equation;
v² = u² + 2ah
v² = 0 + 2 x 2.7 x 20
v² = 108
v = √108
v = 10.39 m/s
Therefore, the final velocity of the vehicle is 10.39 m/s.
Answer: 0.08K
Explanation:
When temperature changes, the corresponding change in thermal energy of a gas is given by:
ΔE (thermal) = 3/2nRΔT
Defining the parameters:
ΔE (thermal) = Increase in thermal energy of the mono atomic gas = 1.0J
n = number of moles of the gas = 1.0mol
R = Ideal gas constant = 8.314J/mol/K
ΔT = change in temperature. This is what we need to find.
Rearranging the equation to make ΔT subject of the formula,
ΔT= 2 x ΔE (thermal) / (3 x n x R)
Therefore, ΔT = 2 x 1.0J / (3 x 1.0mol x 8.314J/mol/K)
ΔT = 2.0J / 24.942J/K
ΔT = 0.0802K
ΔT = 0.08K
The temperature change of 1.0mol of a monoatomic gas if its thermal energy is increased by 1.0J is 0.08K.
