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.
The relationship between a car and energy is that the car uses gas to produce speed within energy needs to be powered
Check the picture below.
now, for 6 triangles, well, simply 6*6.
The scientist is likely to be studying kinematics.
Kinematics is the branch of science, specifically physics, which is concerned with the motion of objects without reference to the forces that induce this motion. An example of kinematics is studying the change in velocity of an object over time or the distance covered by an object in a specified amount of time.
Answer:
the voltage across each resistor is one third of the battery voltage
Explanation:
In a series circuit, the current is constant throughout the circuit, so the battery voltage is equal to the sum of the voltage drop in each part of the series circuit.
V = i (R₁ + R₂ + R₃)
in the exercise indicate that all resistance has the same value
R₀ = R₁ = R₂ = R₃
V = i 3 R₀
V
= 3 V₀
V₀ = i R₀
V₀= V / 3
the voltage across each resistor is one third of the battery voltage
