1) Time to get the highest point of it pathway>
Vf = Vo - g*t
Vf = 0 (condition of maximum height)
Vo = 5.33 m/s
g = 9.81 m/s
=> t = Vo / g = 5.33 m/s / 9.81 m/s = 0.543 s
2) Time to return from the highest point = time to get to the highest point = 0.543 s
Total time = 0.543s + 0.543 s = 1.086 s ≈ 1.09 s
Answer: 1.09 s
Answer: 50π m ≈ 157 m
Explanation:
100 rev/min (2π rad/rev) / (60 sec/min) = 3⅓π rad/s
d = ωrt = 3⅓π(0.50)(30) = 50π m ≈ 157 m
The answer would be (c) above 10 because 4 is basic 5 to seven is also basic and 7 is neutral.
Answer:
the bowling ball, because it has more mass and therefore more inertia
Explanation:
As per law of inertia we know that if an object is having more inertia then it is difficult to change state of motion.
Inertia is the property of mass of an object which always resist to change the state of motion of the object.
If an object has more inertia then it is more difficult to change the state of motion.
Now we know that we have one bowling ball and one basket ball, since bowling ball is having more mass then it must have more inertia so it is difficult to start the motion in bowling ball.
So correct answer will be
the bowling ball, because it has more mass and therefore more inertia
Answer:
625 nm
Explanation:
For constructive interference, the expression is:

Where, m = 1, 2, .....
d is the distance between the slits.
The formula can be written as:
....1
The location of the bright fringe is determined by :

Where, L is the distance between the slit and the screen.
For small angle , 
So,
Formula becomes:

Using 1, we get:

For two fringes:
The formula is:

For first and second bright fringe,

Given that:

d = 2.14 mm
L = 1.90 m
Also,
1 mm = 10⁻³ m
So,

d = 2.14×10⁻³ m
Applying in the formula,


Also,
1 m = 10⁹ nm
So wavelength is 625 nm
