Answer:
The softball hits the ground first because it is less affected by air resistance.
Explanation:
Answer
Speed of 320 gram cart will be 0.377 m /sec
Explanation:
We have given mass of the air track
Velocity of the air track
Mass of the cart
Cart is at stationary so velocity of cart
Now according to conservation of momentum
Answer:
It would be 2600
Explanation:
M/S stands for meters per second. If it moved 1 meter for 2600 seconds, than it would be 2600. You just multiply 2600 by 1! I hope this helps :D
Answer:
E1 = 10.15 * 10^4 N/C
E2 = 0
E3 = 10.15 *10^4 N/C
Explanation:
Given data:
Two 13 cm-long thin glass rods ( L ) = 0.13 m
charge (Q) = +11nC
distance between thin glass rods = 4 cm .
<u>Calculate the electric field strengths </u>
electric charge due to a single glass rod in the question ( E ) =
equation 1 can be used to determine E1, E2 and E3 because the points lie within the two rods hence the net electric field produced will be equal to the difference in electric fields produced
applying equation 1 to determine E1
E1 = ( distance from 1 rod is 0.01 m and from the other rod is 0.03 )
=
= 10.15 * 10^4 N/C
applying equation 1 to determine E2
E2 =
therefore E2 = 0
E1 = E3
hence E3 = 10.15*10^4 N/C
Answer:
If the length is doubled, the period will increase by a factor of √2 .
Explanation:
For Simple Pendulum
T = 2π√(L/g) -----------------(1)
Where T is time period, L is length and g is acceleration due to gravity
Now,
If we double the length,
T = 2π√2L/g
T = √2(2π√(L/g)
From (1), We get
T = √2(T)
So,
If the length is doubled, the period will increase by a factor of √2 .
