Answer:
Time = 0.3256 sec
Explanation:
Velocity = displacement / time
43=14/t
So the time =14/43
t=0.3256 sec
Answer:
0.2 mm
Explanation:
Assuming the Caliper has 1 mm marks on the main scale. Again, we assume that the 20 division coincides with the 16 main scale division, then we can find the least count by saying
For the given Vernier calipers,
Let one main scale division be = 1 mm.
Since there are 20 Vernier scale divisions that happen to be equal to 16 Main Scale Divisions, we can calculate that
1 Vernier Scale Division = 16/20 Main Scale Division
1 Vernier Scale Division = 0.8 mm.
The least count is finally calculated by saying that
Least Count = 1 Main Scale Division - 1 Vernier Scale Division
Least Count = 1 - 0.8
Least Count = 0.2 mm
Therefore, from the assumptions made above, the least count is 0.2 mm
Answer:
The induced current in the resistor is I = BLv/R
Explanation:
The induced emf ε in the long bar of length, L in a magnetic field of strength, B moving with a velocity, v is given by
ε = BLv.
Now, the current I in the resistor is given by
I = ε/R where ε = induced emf in circuit and R = resistance of resistor.
So, the current I = ε/R.
substituting the value of ε the induced emf, we have
I = ε/R
I = BLv/R
So, the induced current through the resistor is given by I = BLv/R
Provided the projectile is landing at the same elevation as it is launched from, it is 45 degrees
