Answer:

As the earth is an oblate spheroid, its radius near the equator is more than its radius near poles. Since for a source mass, the acceleration due to gravity is inversely proportional to the square of the radius of the earth, it varies with latitude due to the shape of the earth.

Formula: g = GM/r2

Dimensional Formula: M0L1T-2

Values of g in SI: 9.806 ms-2

The cable supporting a 2130-kg elevator has a maximum strength of 2.18×104 n . what maximum upward acceleration can it give the

Vlada [557]

Answer;

=0.43 m/s²

Solution;

There will be the tension in the cable, T, upwards and the weight of the elevator, mg, downwards.

By Newton's second law, the sum of the forces will be equal to mass×acceleration.

Resultant force = m × a

Then T - mg = ma so the tension in the cable is

T = m(g+a)

The cable will break when T = 21,800 N

Solving for a, that happens when

a = 21800/2130 - g

= 10.23 - g (in m/s^2)

If you're using g = 9.8 m/s^2

Then the maximum acceleration allowed is 10.23-9.8 = 0.43 m/s^2

A ship is to reach a place 10° south of west. In what direction should it be steered if declination at the place is 17° west?.

Readme [11.4K]

The direction is 7⁰ from west to the south.

We need to know about the degree and direction to solve this problem. The angle between west and south is 90⁰.

From the question above, we know that

Position = 10⁰ south of west

Destination = 17⁰ south of west

Hence, the direction of the ship should be

Direction from west = Destination - Position

Direction from west = 17⁰ - 10⁰

Direction from west = 7⁰

The direction is 7⁰ from west

Direction from south = Destination - Position

Direction from south = (90⁰ - 17⁰) - (90⁰ - 10⁰)

Direction from south = -7⁰

The direction is 7⁰ to the south.

Hence, the direction is 7⁰ from west to the south.

A gold bar has a volume of 4.7 cm3 and a density of 19.3 g/ cm3. What is its mass?

Sunny_sXe [5.5K]

Answer:

Mass of the gold bar is 90.71 gram.

Explanation:

Given:

volume = 4.7 $cm^{3}$

density = 19.3 $\frac{g}{cm^{3}}$

To find:

mass = ?

Formula used:

density = $\frac{mass}{volume}$

Solution:

density is given by,

density = $\frac{mass}{volume}$

mass = volume × density

mass = 4.7 × 19.3

mass = 90.71 g

Mass of the gold bar is 90.71 gram.

For incident ray C, the angle of refraction is 90°. The refracted ray C has the smallest amount of energy of any refracted ray.

Usimov [2.4K]

Answer:

Explanation:

When a ray of light travels into rarer medium from the denser medium and the angle of refraction is 90° so the angle of incidence in the denser medium is called critical angle for that pair of media.

Here, the angle of refraction is 90°, so the angle of incidence C is called the angle of incidence which is equal to the critical angle.
