Answer:
there is no motion for victor
Answer:
0.6 Ω
Explanation:
As shown in the diagram below,
Since the resistance and the ammeter are connected in series,
(i) The same amount of current flows through them.
(ii) The sum of their individual individual voltage is equal to the total voltage of the circuit.
Applying ohm's law,
V = IR................ Equation 1
Where V = Voltage across the ammeter, I = current flowing through the ammeter, R = resistance of the ammeter.
make R the subject of the equation
R = V/I............... Equation 2
Given: V = 1.2-0.9 = 0.3 V, I = 0.5 A.
Substitute into equation 2
R = 0.3/0.5
R = 0.6 Ω
Answer:
d = 3.56 x 10⁻⁴ m = 0.356 mm
Explanation:
The diameter of the aperture can be found using the following formula:
where,
y = distance between dark rings = 1.65 mm = 1.65 x 10⁻³ m
λ = wavelength = 490 nm = 4.9 x 10⁻⁷ m
L = distance between screen and aperture = 1.2 m
d = diameter of aperture = ?
Therefore,
<u>d = 3.56 x 10⁻⁴ m = 0.356 mm</u>
A skater can spin faster by pulling her arms closer to her body or spin slower by spreading her arms out from her body due to conservation of angular momentum.
What is conservation of angular momentum?
- Conservation of angular momentum is a physical property of a spinning system such that its spin remains constant unless it is acted upon by an external force, or to put in another way, the speed of rotation is constant as long as net torque is zero.
- Angular momentum, sometimes also referred to as spin, is determined by an object's mass, its velocity and distance of an object's mass from the point of rotation.
- The nearer the mass is to its axis point or the more consolidated it is around that axis the greater its velocity.
