Yeah what do you want me to answer for this question?
F = m • a
What we know:
- Gravity: 9.8 m/s
- Force: 490 N
Equation derived:
m = F/a
m = 490/9.8
= 50 kg
Answer:
The spacing between the slits is
Explanation:
From the question we are told that
The wavelength of the light is 
The distance of the slit from the screen is 
The number of bright fringe is 
The length the fringes span is 
The fringe width (i.e the distance of between two successive bright or dark fringe) is mathematically represented as

Where d is the distance between the slits
is the fringe width which can also be evaluated as

Substituting values


Making d the subject of formula in the above equation

Substituting values

Answer:
A car weighing 15 grams
Explanation:
According to the equation that shows the relationship between mass (m), force (F), and acceleration (a) i.e. F = ma, it can be seen that with a constant force, the mass is inversely proportional to the acceleration.
This means that an increase in mass of an object denotes a decrease in acceleration of that object and vice versa. Hence, according to this question, when pushed with the same amount of force, a car with the least mass will move faster. This car is the car weighing 15grams.
Answer:
velocity 1 second later = 59.8 m/s
Explanation:
Velocity final = Velocity initial + acceleration • time
Velocity final = 50m/s + 9.8m/s/s • 1s
Velocity final = 59.8 m/s
