Question

What is the weight in dynes of a 13.0-ton lunar probe when it is on the surface on the Moon? (not metric ton) The acceleration due to gravity at the Moon's surface is g = 162.6 cm/s.

Answer 1

Answer:
`2.11* 10^9dyne`

Step-by-step explanation:

Weight of an object is the force acting on an object by virtue of its mass.

weight=
`mass* acceleration`

Given : mass = 13.0 ton =13000 kg (1ton =1000 kg)

acceleration due to gravity =
`162.6cm/s^2=1.626m/s^2`

`(1m=100cm)`

Putting in the values we get,

Weight=
`13000kg* 1.626m/s^2=21138kgms^(-2)=21138N`

`(1kgms^(-2)=1Newton(N))`

Weight=
`21138* 10^5=2.11* 10^9dyne`

`(1Newton(N)=10^5dyne)`
