The forces move strongly towards the left by 1N
Given the following
Force towards the right = 4N
Force towards the left = 5N
Note that the force acting towards the left is negative, hence the force acting towards the left is -5N
Take the sum of force
Resultant force = -5N + 4N
Resultant force = -1N
This shows that the forces move strongly towards the left by 1N

Answer:
R = -2500N
Explanation:
Use formula ΣF = Ma. We can split the Net Force into two parts: Fe - Ff = Ma.
Fe is the force developed by the engine: 4000N
Ff (R) is the air resistance projected on the vehicle. This is the value we're looking for.
Mass: 1000kg
Acceleration: 1.5m/s^2
Next, just plug in the values and solve.
▪4000N - Ff = (1000kg)(1.5m/s^2)
▪Ff = 1500N - 4000N
▪Ff = -2500N
R = -2500N.
The air resistance acting on the car is R = -2500N.
Answer:
4.9N
Explanation:
The formula for weight is F = ma.
You plug in the mass of 0.5kg and an acceleration of 9.8 to get
F = (0.5)(9.8)
F = 4.9N
The cloud would most likely get bigger in size. If humidity is high, there is a lot of water avalible to be made into a cloud. The larger the amount of water, the more clouds that can form.
Answer:
Part A: 16.1 V
Part B: 20.5 V
Part C: 21.5%
Explanation:
The voltmeter is in parallel with the 4.5-kΩ resistor and the combination is in series with the 6.5-kΩ resistor. The equivalent resistance of the parallel combination is given as
Part A
The voltmeter reading is the potential difference across the parallel combination. This is found by using the voltage-divider rule.
Part B
Without the voltmeter, the potential difference across the 4.5-kΩ resistor is found using the same rule as above:
Part C
The error in % is given by
