The acceleration due to gravity on the surface of mars is about one third the acceleration due to gravity on earth’s surface. the weight of a space probe on the surface of mars is about a. the same as its weight on earth’s surface. b. three times greater than its weight on earth’s surface. c. one third its weight on earth’s surface. d. nine times greater than its weight on earth’s surface.

The correct answer to the question is : C) One third its weight on Earth's surface.

EXPLANATION :

Before coming into any conclusion, first we have to understand the weight of a body.

The weight of a body is defined as the force with which it is attracted towards the centre of stars, planets or satellites.

Quantitatively, it is defined as the product of mass of the body with acceleration due to gravity.

Mathematically weight W = mg

Here, m is the mass and g is the acceleration due to gravity.

Mass of a body is constant for non-relativistic situation.

Hence, weight of a body is dependent on acceleration due to gravity.

As per the question, the acceleration due to gravity of Mars is three times less as compared to the acceleration due to gravity of earth.

The weight of a space probe on Mars is given as A.

The weight of the space probe on earth will be 3A.

Hence, the weight of the space probe on Mars is one third its weight on Earth's surface.

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50

the answer is a 3.8cm
