Hooke's Law says that F=-kx where k is the spring constant measured in N/m (newtons per meter)
Well first of all, a planet doesn't have a semimajor axis, although it's orbit does.
In an orbit with a smaller semimajor axis, the planet moves faster, and its orbital period is shorter.
That's why the International Space Station circles the Earth in less time than the Moon does.
Answer:
the two skaters will meet at a distance of 9.75 m from the initial position of 35 kg skater
Explanation:
Since there is no external force on the system of two skaters
So the two skaters will meet at the position of their center of mass
so let the position of 35 kg skater is origin
then the position of other skater is 15 m
now by the formula of center of mass we have
so the two skaters will meet at a distance of 9.75 m from the initial position of 35 kg skater
Answer:
By applying a force of one Newton, one can hold a body of mass of 102 gram.
Explanation:
- Force is the pull or push of an object. It can be mathematically measured as, F= m* g.
where, F= force in newton
m= mass in kg
g= acceleration due to gravity ( )
F= m* 9.8
or, m= = 0.102 kg
or, m= 102 gram.
- Hence, 102 gram mass can be hold by one Newton force.
779,247 J is the amount of heat released.
<u>Explanation:</u>
The equation that gives the amount of heat supplied is
Where,
E or Q – amount of heat supplied
m- mass
- specific heat capacity of Aluminium
– temperature variation caused by heat change
The amount of heat energies that causes the temperature to vary or 1 K per kg of the material is known as specific heat capacity (c)
Here, Given data:
– 0.900 J/g.K
To convert gram into kilogram, multiply and divide by , we get
Specific heat capacity of aluminum = 900 J/kg. K
m – 5.89 kg
By substituting the known values in the above equation, we get
