Answer:
103063860 Pa
Explanation:
= Density of seawater = 1030 kg/m³
g = Acceleration due to gravity = 9.81 m/s²
h = Depth at which pressure is being measured = 10.2 km
The gauge pressure is given by
Therefore, the gauge pressure at a depth of 10.2 km is 103063860 Pa
Answer:
Explanation:
mass of particle m = 2 x 10⁻⁶ kg
charge q = 1 x 10⁻⁹ C
electric field E = 2000 N/C
force on charge = E q
= 2000 x 1 x 10⁻⁹
acceleration = force / mass
= 2000x10⁻⁹ / 2 x 10⁻⁶
= 1 m /s²
initil velocity u = 6 m /s
distance s = 4 x 10⁻²
time = t
s = ut + .5 t²
4 x 10⁻² = 6t + .5 x 1 x t²
t² + 12t - .08 = 0
= .0067 s .
= 6.7 ms .
consider the motion in vertical direction
v = initial velocity in the vertical direction = ?
v' = final velocity in the vertical direction at the highest point = 0 m/s
a = acceleration due to gravity = - 9.8 m/s²
h = maximum height = 12.2 m
Using the kinematics equation
v'² = v² + 2 a h
0² = v² + 2 (- 9.8) (12.2)
v = 15.5 m/s
let assume that velocity of launch be v₀
θ = angle of launch = 13
vertical component of the velocity of launch is given as
v = v₀ Sinθ
15.5 = v₀ Sin13
v₀ = 69 m/s
Answer:b
Explanation:
because a satellite is used to tell the exact location and to communicate
Answer:
When all of the domains are aligned, the material is said to be magnetically saturated. When a material is magnetically saturated, no additional amount of external magnetization force will cause an increase in its internal level of magnetization.
