Answer:
6.03 m/s
Explanation:
<em>Average speed = total distance traveled/total time taken</em>
7 = 450 + 100/total time
total time = 550/7 = 78.57 s
<em>Speed of camel on the bicycle = distance/time</em>
25 = 100/time
time = 100/25 = 4 s
Total time = 78.57 s
Time spent riding bicycle = 4 s
<em>Time spent walking = total time - time spent riding bicycle</em>
= 78.57 - 4 = 74.57 s
<em>Speed of walking = distance walked/time spent walking</em>
= 450/74.57
= 6.03 m/s
the force is given by the equation
q*v*B [email protected]
thus it will be
(1.6*10^-19)*(7.8*10^4)*(3)*1/√2 which gives 2.6*10^-14 N
Water=hydrosphere
wind=atmosphere
ice=cryosphere
organisms=biosphere
I think!!
Answer:
Explanation:
mass of alpha particle, m = 4 u = 4 x 1.67 x 10^-27 kg
charge, q = 2 e = 3.2 x 10^-19 C
radius, r = 3.45 cm
Magnetic field, B = 1.67 T
(a) let v be the speed
v = 2760000 m/s
(b) Let T be the period of revolution
T = 7.85 x 10^-8 seconds
(c) Kinetic energy, K =0.5 x mv²
K = 0.5 x 4 x 1.67 x 10^-27 x 2760000 x 2760000
K = 6.36 x 10^-15 J
(d) kinetic energy, K = e V
where, V is the potential difference
6.36 x 10^-15 = 1.6 x 10^-19 x V
V = 39754.35 V
It add to the pollution to the air and the waste is throw into the ocean
