Can track storms at different altitudes

OlgaM077 [116]

The radars, weather satellites and the several highly accurate barometers are used to track the different storms at different altitudes.

Further Explanation:

The storms at different altitudes are generated due to pressure variation in the different regions of the air. This pressure variation in the air is the main cause of the formation of the storms.

These storms can be easily tracked by means of the Radars and other weather forecasting satellites which keep a track of the variation in the trends of the pressure and temperature in the particular regions.

The trends of the strength of the winds can also predict a lot about the direction of motion of the winds. The highly accurate barometers are used to measure the strength of the storms originating at the different altitudes.

Thus, the radars, weather satellites and the several highly accurate barometers are used to track the different storms at different altitudes.

Four point charges, each having a magnitude of 2:00 C, are fixed at the corners of a square whose edges are 4:00m long. Find the

Vikki [24]

Answer:

Explanation:

Distance of each of the charges from the center are equal . If this distance be d

d = .5 x length of diagonal of square

length of diagonal = 4√2

d = .5 x 4√2

= 2√2

potential at a point

V = k Q / r where k is a constant , Q is charge and r is distance of the point from the charge .

k = 9 x 10⁹

Total potential = $\frac{9\times10^9\times3 \times2}{2\sqrt{2} } -$ $\frac{9\times10^9 \times2}{2\sqrt{2} }$

= $\frac{9\times10^9 \times2\times2}{2\sqrt{2} }$

= 9 √2 x 10⁹ V .

Physics !!!!!!!!!!!!!!!!!

madreJ [45]

Answer:

1) v = -0.89 m/s

2) v = 36.5 m/s

Explanation:

1) Given

The mass of the boy, M = 45 Kg

The mass of the skateboard, m = 2 Kg

The initial velocity of the boy and skateboard is zero

According to the law of conservation of linear momentum

MV + mv = 0

V = - mv/M

Substituting the given values in the above equation

V = -2 x 20/ 45

= -0.89 m/s

Hence, the velocity of the boy, v = -0.89 m/s

2) Given

The mass of the boy, M = 47 Kg

The mass of the skateboard, m = 8 Kg

The initial combined velocity of the boy and skateboard, u = 4.2 m/s

The boy jumped off from the skateboard with velocity, V = -1.3 m/s

According to the law of conservation of momentum,

MV + mv = (M + m)u

v = [(M + m)u - MV] / m

Substituting the given values,

v = [(47 + 8)4.2 - 47(-1.3)] / 8

= 36.5 m/s

Hence, the velocity of the skateboard, v = 36.5 m/s

A 6 ft tall person walks away from a 10 ft lamppost at a constant rate of 5 ft/s. What is the rate (in ft/s) that the tip of the

nalin [4]

Answer:

12.5 ft/s

Explanation:

Height of person = 6 ft

height of lamp post = 10 ft

According to the question,

dx / dt = 5 ft/s

Let the rate of tip of the shadow moves away is dy/dt.

According to the diagram

10 / y = 6 / (y - x)

10 y - 10 x = 6 y

y = 2.5 x

Differentiate both sides with respect to t.

dy / dt = 2.5 dx / dt

dy / dt = 2.5 (5) = 12.5 ft /s
