Answer:
5 Km/h
Explanation:
From the question given above, the following data were obtained:
Distance travelled = 10 Km
Time = 2 hours
Speed =?
Speed is simply defined as the distance travelled per unit time. Mathematically, it can be represented as:
Speed = distance travelled /time.
With the above formula, we can obtain the speed at which the duck is travelling as follow:
Distance travelled = 10 Km
Time = 2 hours
Speed =?
Speed = distance travelled /time.
Speed = 10 / 2
Speed = 5 Km/h
Thus, the duck is travelling at a speed of 5 Km/h
Answer:
Oi, mate its false

because if an leaf floats down from a tree it is not considered an object for a free-fall
Answer:
The direction of the B-field is in the +y-direction.
Explanation:
The corresponding formula is
This means, we should use right-hand rule.
Our index finger is pointed towards +x-direction (direction of velocity),
our middle finger should point towards the direction of the B-field,
and our thumb should point towards the +z-direction (direction of the force).
Since our middle finger in this situation points towards +y-direction, the B-field should be in +y-direction.
The angle of refraction would be further less
Answer:
Charge on each metal sphere will be
Explanation:
We have given number of electron added to metal sphere A
As both the spheres are connected by rod so half -half electron will be distributed on both the spheres.
So electron on both the spheres
We know that charge on each electron
So charge on both the spheres will be equal to
So charge on each metal sphere will be equal to
