Answer:
577g
Explanation:
Given parameters:
Temperature change = 5.9°C
Amount of heat lost = 427J
Unknown:
Mass of the block = ?
Solution:
The heat capacity of a body is the amount of heat required to change the temperature of that body by 1°C.
H = m c Ф
H is the heat capacity
m is the mass of the block
c is the specific heat capacity
Ф is the temperature change
Specific heat capacity of lead is 0.126J/g°C
m = H / m Ф
m = 
= 577g
Mass of the lead block is 577g
Answer:
the motion of an object in a circular path , in a fixed orbit
A is the correct answer: 100 degrees C is the boiling point of water, just subtract 82 from 100.
Answer:
option B
Explanation:
The correct answer is option B
Comets are the frozen snowball that is made of different gases and which rotates around the sun.
Comets are generally icy but when comets come near to the sum they get warm and release gasses which can be seen from the earth.
Comet produces a visible atmosphere or coma.
examples of comets are Halley's Comet, Comet Encke.
The orbit of comets is entirely beyond the orbit of Neptune.
An object in motion tends to stay in motion an oject at rest stays at rest.
