Answer:
0.5A
Explanation:
V=IR where V is 1.5V, R is 3 ohms
Hence 1. 5= I x 3
1.5/3 =I
I =0.5 A
Current is 0. 5 amperes
d. none of the above
pressure affects volume not the other way round
Answer:
<em>10.09 units</em>
Explanation:
For the A
Ax = -8.0 units
Ay = 6.0 units
The resultant vector = Ra =
Ra =
= 10 units
For B
Bx = 1.0 units
By = -1.0 units
The resultant vector = Rb =
Rb =
=
units
Adding these two vectors A and B together, magnitude of vector R is
R = 
R =
= <em>10.09 units</em>
The outer surface of the glass expands faster than the inside surface since glass is a fairly good thermal insulator. The outer surface tries to expand without the inner surface doing so at the same time. This is the secret of Pyrex glass. It is more conductive to heat and the inner and outer surface expand (and contract) at the same time.
