Answer:
C
Explanation:
Using the two formulas q =CV and C =<em>∈A/d where q = charge, C = Capacitance, V =Voltage, ∈=permittivity of dielectric, A = area of plates and d = distance between plates. </em>Increasing the plate separation decreases the Capacitance thereby decreasing the charge also.
Answer:
MASS is measured in KILOGRAMS
Weight is measured in NEWTONS
Explanation:
Only mitotic divisions change the zygote to embryo. The other sentences are related to the way zygote is created
Answer:
C. 0 J
Explanation:
When an object moves in a circle, friction provides the centripetal force. Hence, it is acting towards the centre of the circle. The displacement of the object is tangential to the circle at the point of interest. Hence, the angle between the frictional force and the displacement is 90°.
Work done is given by
<em>W</em> = <em>Fd</em> cos <em>θ</em>
where <em>F</em> is the force, <em>d</em> is the displacement and <em>θ</em> is the angle between them.
<em>W</em> = <em>Fd</em> cos 90° = 0 J
Hence, the work done by friction is 0 J.
Answer:
A) C is 2 units towards right
B) C is 9 units towards right and 3 units towards up
C) C is 4 units towards right and 1 unit towards down
Explanation:
Drawings are given in the attachment.
A)Since,
A is 4 units towards right,
B is 1 unit towards left,
Then,
C is 2 units towards right.
B) Since,
A is 4 units towards right and 2 units towards up,
B is 1 unit towards left,
Then,
C is 9 units towards right and 3 units towards up.
C) Since,
A is 4 units towards right and 2 units towards up,
B is 1 unit towards right, and 1 unit towards down
Then,
C is 4 units towards right and 1 unit towards down.
