The molecular geometry of both F2 and HF is linear.There are only two atoms which are covalently bonded and thus, the bonding scheme with the atoms looks like this;
F --- F
H---F
So, both are linear.
Explanation:
t = usin©/g
Where t is the time to reach the maximum height
Time spent in air is T = 2t
Hence, T = 2usin©/g
T = 2 x 20 x sin 65°/ 9.8
T = 3.69s
Answer:
Explanation:
Formula of acceleration a = fm
A = 68 x 386
= 26248
Answer:
Radius of bigger loop(R) =4.5cm
Explanation:
Consider a circular path of radius r around the wire. The magnetic field along that path is given by
;
∫B*dl = k*I where I is the current enclosed. From symmetry, ∫B*dl = 2*π*r*B
B = K*I/r, so the magnetic field varies inversely as the loop radius and directly as the current.
The smaller loop current to radius ratio is 12/2.7
The bigger loop current to radius ratio is = 20/R
12/2.7 = 20/R
R = (20 * 2.7)/12
R=54/12
R=4.5cm
