Answer:
The specific heat capacity of molybdenum is
0.2696 joule/gram
Explanation:
Step one
Given that
Mass of molybdenum Mm =237g
Temperature of molybdenum
T1=100°c
Mass of water MW =244g
Temperature of water T2= 10°c
Final temperature T3 =15.3°c
Step two :
We know that the specific heat capacity of water Cw 4.186 joule/gram
But Specific heat capacity of molybdenum Cm?
We know that the quantity of heat transfered can be expressed as
Q=Mm*Cm(T1-T3)+MW*Cw(T2-T3)
since the system attained thermal equilibrium then the expression
Is
=Mm*Cm(T1-T3)=MW*Cw(T3-T2)
Substituting our values into the equation we have
237*Cm(100-15.3)=244*4.186(15.310)
20073.9Cm=5413.3352
Cm=0.2696 joule/gram
Specific heat capacity of molybdenum is 0.2696 joule/gram
Answer:
The amount of effort needed to move the box is 187.5 N
Explanation:
weight of the box = load moved by the ramp, L = 750 N
mechanical advantage of the ramp, MA = 4
effort needed to move the box, E = ?
Mechanical advantage is given as = Load / Effort
Effort = Load / Mechanical advantage
Effort = 750 / 4
Effort = 187.5 N
Therefore, the amount of effort needed to move the box on to the truck using a ramp is 187.5 N
Answer: False
Explanation: The circulatory system of the body consists of the heart, blood vessels and blood. The deoxygenated blood from the body is carried to the heart.
Here, the deoxygentaed blood is converted into oxygenated by removing carbon dioxide from them and making it oxygenated.
The impure blood from the body is collected by the right ventricle and transported to the lungs for purification and then transported to the body.
