Answer:
water forms hydrogen bonds
Explanation:
Answer:
a)
b) north edge will rise up
Explanation:
torque on the coil is given as

where N is number of loop = 9 loops
i is current = 7.80 A
-B -earth magnetic field = 
A- area of circular coil


A =0.015 m2
PUTITNG ALL VALUE TO GET TORQUE


b) north edge will rise up
The shadow that will be protected on the ground will represent the hawk's horizontal position. therefore it will move at the hawk's horizontal velocity component, which is:
5*cos(60) = 2.5 m/s
Answer:
C
Explanation:
velocity = displacement (m) / change of time (s)
velocity = (400 + 300) / (100 + 400)
velocity = 1.4 m/s
