Whale sharks swim forward while ascending or descending. They swim along a straight-line path at a shallow angle as they move fr

om the surface to deep water or from the depths to the surface. In one recorded dive, a shark started 50 m below the surface and swam at 0.85 m/s along a path tipped at a 13 ∘ angle above the horizontal until reaching the surface.

Although you didn't provide the question, I'm here to clarify the issue and guide you in locating the necessary information.

1) The shark rises at an angle of 13°, calculated as follows:

Vertical ascending speed = 0.85m/s * sin(13°)

Horizontal speed = 0.85m/s * cos(13°)

2) The distance the shark covers while ascending is determined as follows

Vertical ascent length = 50 m

Horizontal distance, y:

\frac{y}{50} = \frac{0.85sin(13)}{0.85cos(13)}

This gives y = 50 * tan(13°)

=> y = 11.54 m.

3) In conclusion:

1) The shark traveled 50 m upward vertically and 11.54 m horizontally.

2) To find the length of the path taken by the shark, we can use Pythagoras' theorem:

hypotenuse^2 = (50m)^2 + (11.54m)^2 = 2633.25m^2

hypotenuse = 51.35m

Consequently, the shark swam 51.35 m to surface.

A shuttle on Earth has a mass of 4.5 E 5 kg. Compare its weight on Earth to its weight while in orbit at a height of 6.3 E 5 met
ValentinkaMS [2425]

Response:

83%

Clarification:

At the surface, the weight can be expressed as:

W = GMm / R²

where G denotes the gravitational constant, M represents the Earth's mass, m signifies the shuttle's mass, and R is the Earth's radius.

When in orbit, the weight is given by:

w = GMm / (R+h)²

where h indicates the shuttle's altitude above Earth's surface.

The weight ratio is as follows:

w/W = R² / (R+h)²

w/W = (R / (R+h))²

For R = 6.4×10⁶ m and h = 6.3×10⁵ m:

w/W = (6.4×10⁶ / 7.03×10⁶)²

w/W = 0.83

Thus, the shuttle maintains 83% of its weight as it orbits.

ValentinkaMS [2425]

Conclusion:

The total net force acting on the objects is 16 N, directed towards the right.

Clarification:

It is stated that,

The force exerted by the dog, F_1 = 32\ N (to the right)

The force exerted by Simone, F_2 = -16\ N (backward)

Here, assume the backward direction is negative and the right direction is positive.

The net force will move in the direction where the larger force is present. The net force can be calculated as:

F=F_1+F_2

F=32+(-16)

F = 16 N

Thus, the net force amounts to 16 N, acting towards the right.
