The initial velocity of the car is 11 m/s.
Explanation:
- Here, we can use the equations of motions.
- The first of equation of motion is v = u + at, where v is the final velocity, u is the initial velocity, a is the acceleration, and t is the time.
- The given parameters are,
Final velocity, v = 20 m/s
acceleration of the care, a = 2 m/
time, t = 3 s
Initial velocity, u = ?
- Hence, the equation can be written as u = v - at
once you substitute all these vales, you will get u = 11 m/s
The answer is differentiation. Differentiation is worried about things like rates and increasing velocities, slants and bends ect. Differentiation finds the immediate rate of progress of a capacity as for an autonomous variable. It is utilized when an amount demonstrates non-Linear variety. You can discover the speed of a molecule at a specific time by knowing the separation as an element of time.
Answer:
The new gravitational force will be of 4.5 units
Explanation:
Recall that the formula for the gravitational force between two objects of masses m1 and m2 separated by a distance d is given by:
in our case, we are told that such gives 72 units of force:
Then we change the distance between the objects to 4 times the original (4 * d), such will produce a new gravitational force Fg':
Therefore the new gravitational force would be of 4.5 units
Answer:
Gas 2, Gas 3, Gas 4, Gas 5 is the order of decreasing strength of inter-molecular forces.
Explanation:
The strength increases as there is a decrease in the vanderwaals constant and vice versa.
