1250 N of force is required to accelerate a 250 kg motorcycle at a rate of 5 m/
.
<u>Explanation:</u>
As per the second law of motion stated by Newton, the net unbalanced external force acting on any object is directly proportional to the product of mass and acceleration experienced by the object.
As here the object is given as motorcycle of mass 250 kg. Also the acceleration exhibited by the motorcycle is stated as 5 m/. So from the Newton's second law of motion,
Net force = Mass of the motorcycle× Acceleration of the motorcycle
Net force = 250 × 5 = 1250 N.
Thus, 1250 N of force is required to accelerate a 250 kg motorcycle at a rate of 5 m/.
Answer:
Explanation:
given that
Radius =0.75m
Cnet=0.13nC
a. Electric field inside the sphere located 0.5m from the center of the sphere.
The electric field located inside the sphere is zero.
b. The electric field located 0.25m beneath the sphere.
Since the radius is 0.75m
Then, the total distance of the electric field from the centre of the circle is 0.75+0.25=1m
Then
E=kq/r2
K=9e9Nm2/C2
q=0.13e-9C
r=1m
Then,
E= 9e9×0.13e-9/1^2
E=1.17N/C. Q.E.D
It was not the first time that a person who was in a few weeks ago, I
Answer:
b) increase.
c) decrease.
d) Fringe is said to be a missing fringe when interference maxima overlap with diffraction minima.
Explanation:
a ) Young's interference is the interference phenomenon related to the light waves. Interference is the superposition of light waves . It proved the wave nature of light . Interference can be either constructive or destructive.
b) If the distance between the two slits increases, the number of fringes also increases. d sinθ = m λ. Here d is the slit width and m is the order of fringes. It shows that as d increases, m also increases.
c) Similarly, as d decreases , number of fringes decrease.
d) Fringe is said to be a missing fringe when interference maxima overlap with diffraction minima.
Answer:
As the voltage increases, the current flowing through the circuit increases while the resistance of the resistor remains constant.
Explanation:
Ohm's law states that the current flowing through a circuit is directly proportional to the applied voltage.
V = IR
where;
I is the current
R is the resistance
V is the applied voltage
Based on this law (Ohm's law), as the voltage increases, the current flowing through the circuit increases while the resistance of the resistor remains constant.
