Answer:
a)Counterclockwise
b)ω=2 rad/s
Explanation:
Given that
Object at = --2 m
r= - 2 m
Velocity pf object V = - 4 m/s
We know that
r= - 2 i m
V= - 4 j m/s
- 4 j= ω x (- 2 i)
ω should be in counter clockwise (k) to satisfy the above equation.
It means that the direction of object will in counter clockwise.
4 = ω x 2
ω=2 rad/s
So object velocity at 2 m will be 2 rad/s.
Answer:
No, a liter is equal to 1000 milliliters
Well I don't know !
Let's work it out:
Weight = (mass) x (local acceleration of gravity)
117.6 N = (12 kg) x (gravity)
Gravity on Planet A = (117.6 N) / (12 kg)
= 9.8 m/s² exactly
The gravity on Planet-A is so close to Earth gravity
that nobody could ever tell the difference without
making sensitive measurements.
They are essentially equal.
When waves travel across strings, the larger the tension of the string the faster the velocity of the wave. This is because of the equation:
v = the square root of (T/(m/L)) where T is the tension, m the mass of the string, and L the length of the string
Hope this helps!
