The periodic sign of magnesium is ------> mg
Answer:
here we can say that acceleration of the satellite is same as the gravitational field due to Earth at that location
Explanation:
As we know that gravitational field is defined as the force experienced by the satellite per unit of mass
so we will have
now in order to find the acceleration of the satellite we know by Newton's II law
so we will have
so here we can say that acceleration of the satellite is same as the gravitational field due to Earth at that location
The kinetic energy (KE) is 250 J and the gravitational potential energy (GPE) is 392 J
Answer:
Due to application of heat on a saturated solution, the interparticle space increases due to increase in the kinetic energy of the particles which allows more solutes to dissolve in the solution thereby making it unsaturated.
Answer:
0.048J/g°C
Explanation:
Given parameters:
Mass of Mercury = 25g
Initial temperature = 25°C
Final temperature = 155°C
Amount of heat absorbed = 455J
Unknown:
Specific heat capacity of mercury = ?
Solution:
To solve this problem, we use the expression below:
Q = m x C x Δt
Q is the heat absorbed
m is the mass
C is the unknown specific heat capacity
Δt is the change in temperature;
455 = 25 x C x (155 - 25)
455 = 25 x C x 130
C = 0.048J/g°C
