To convert the amount in moles to units of grams, we need the atomic mass of nickel which is 58.69 g/mol. We multiply the number of moles to the atomic mass which cancels moles leaving us with units of grams. 2.63 moles ( 58.69 g/mol ) = 154.35 g Nickel Hope this answers the question. Have a nice day. Posted in Physics In 2004 astronomers reported the discovery of a large Jupiter-sized planet orbiting very close to the star HD 179949 (hence the term "hot Jupiter"). The orbit was just 19 the distance of Mercury from our sun, and it takes the planet only 3.09 days to make one orbit (assumed to be circular). What is the mass of the star? Express your answer (a)in kilograms and (b)as a multiple of our sun's mass. I'll tell you how to do it but you must crunch the numbers. Use Kepler's 3rd Law T^2 = k R^3 where k = 4(pi)^2/ GM G =gravitational constant = 6.67300 × 10-11 m3 kg-1 s-2 M = mass of this new planet pi = 3.14159265 T =3.09 days = 266976 seconds R = (579,000,000km)/9 = 64333333.3 km a) Solve Kepler's 3rd Law for M.

A net force of 125 N accelerates a 25.0 kg mass. What is the resulting acceleration?

Explanation:

The acceleration of an object can be calculated by using Newton's second law:

where

F is the net force applied on the object

m is the mass of the object

a is its acceleration

In this problem, we have F=125 N and m=25.0 kg, so we can rearrange the equation to calculate the acceleration:

Force times Mass equals Acceleration.
If the mass increases the number on the left side of the equation increases, thus increasing the right side as well.

The acceleration due to gravity on Earth is 9.80 m/s2. An African elephant can have a mass up to 6,050 kg. What is its weight?

The weight on earth is equal to m*g, where m is the mass and g is the gravitational force. 6050 (m) * 9.8 (g) = 59290 Newtons.

A student hangs a mass of 150 g on a force table at an angle of 150 degrees . If she then hangs a mass of 220 g at 270 degrees. A) at what angle should she hang a mass of 195 g so that the ring is in equilibrium? B) Draw the vectors

Horizontally: 150g*cos150 + 220g*cos270 + 195g*cosΘ = 0
cosΘ = 0.666
Θ = ± 48º
Vertically:
150g*sin150 + 220g*sin270 + 195g*sinΘ = 0
sinΘ = 0.744
Θ = 48º

A sled and rider, gliding over horizontal, frictionless ice at 4.7 m/s , have a combined mass of 80 kg . The sled then slides over a rough spot in the ice, slowing down to 3.4 m/s . What impulse was delivered to the sled by the friction force from the rough spot? Express your answer to two significant figures and include the appropriate units.

Impulse is the change in momentum.
All we need is the momentum before and after.

Momentum  =  (mass) x (speed)

Before:        =  (80 kg) x (4.7 m/s)  =  376 kg-m/s

After:           =  (80 kg) x (3.4 m/s)  =  272 kg-m/s

Change in momentum  =  (376 - 272) =  104 kg-m/s

Notice that when you work with impulse, you're USUALLY calculating

(force) x (time).

The force is in Newtons, and the time is in seconds,
so the impulse is usually in units of

Newton-seconds .

So how can I say that impulse and change of momentum are
the same thing ?  Am I trying to pull a fast one on you ?

Remember that    1 Newton is  1 kg-m/s²

So                       (force) x (time)

=  (Newton) x (second)

=  (kg-m/s²) x (second)  =  kg-m/s .

and  Momentum = (mass) x (speed)  =  (kg) x (m/s)

The units of impulse are the same as the units of momentum !

So when you give an object some impulse, you give it exactly
that much momentum.
