Answer:
Explanation:
Yes , their displacement may be equal .
Suppose the displacement is AB where A is starting point and B is end point .
The car is covering the distance AB by going from A to B on straight line . On the other hand plane goes from A to C , then from C to D and then from D to B . In this way plane reaches B from A on a different path which is longer than path of the car . In the second case also displacement of plane is AB . In the second case distance covered is longer but displacement is same that is AB .
I am absolutely sure that the way how can a moving coil galvanometer can be made into a dc ammeter is of course by connecting a. low resistance across the meter. You should remember that you must connect <span>a shunt resistor straight across the galvanometer. Do hope this answer will help you! Regards.</span>
Explanation:
Let yellow ball be m1 = 0.5kg with u1 = 8 m/s and blue ball be m2 = 0.25 kg with u2 = - 4 m /s respectively.
After collision, blue ball travels 12 m/s.
<u>Using conservation of Linear Momentum</u> :
m1u1 + m2u2 = m1v1 + m2v2
0.5* 8 + 0.25 * - 4 = 0.5 * v1 + 0.25 * 12
v1 = 0 m/sec i.e. <u>Yellow ball comes to rest</u>.
Answer:
Explanation:
It is given that,
The radius of the solid sphere, R = 50 cm = 0.5 m
Charge on the sphere, 
We need to find the magnitude of the electric field r = 10.0 cm away from the center of the sphere. The electric field at point r away form the center of the sphere is given by :
So, the electric field 10.0 cm away from the center of the sphere is 
. Hence, this is the required solution.
We can find the momentum of the rock by using De Broglie's relationship:
where
p is the momentum
h is the Planck constant
is the De Broglie's wavelength
By using
, we find
The momentum of the rock is
where
is the mass and v is its velocity. Rearranging the equation, we find the speed of the rock:
