we know
T=2.pie sqr root(l/g)
l= (sqrof 7/22)*9.8
L= .99 or approx 1m
Answer:
What is the quantity that has the units of m/s²?
- Velocity
- <em><u>Acceleration✓</u></em>
- Force
- Momentum
<em><u>Acceleration</u></em> is the quantity that has the units of m/s².
Explanation:
Acceleration is the rate of change of velocity.
Acceleration=(Final velocity-Initial velocity)/Time.
The cones present on the retina are the cells that help you see the colors.....there are mainly three types....red blue and green, cones but they mix to generate different colours !
Answer:
Option B
Solution:
As per the question:
Length of the suspended wire, l = 16 cm = 0.16 m
Distance between the long wire and the suspended wire, R = 1.5 mm = 0.0015 m
Mass of the 16 cm wire, m = 0.014 kg
Now,
We know that the magnetic field due to the two parallel current carrying straight long wires with current 'I' and the separation 'R' between the wires is given by:
(1)
If the suspended wire floats, force due to its weight is balanced by the magnetic force due to current I:
mg = IBl
Also, from eqn (1):
mg =
mg =
I = 80.19 A
I = 80 A (approx)
