its B 0.225kPa using the formula p=f/A then change the pascals into kpa
Answer:
The net gravitational force on the mass is 
Explanation:
We have by Newton's law of gravity the force of attraction between masses 
Applying vales we get
Force of attraction between 135 kg mass and 38 kg mass is
Force of attraction between 435 kg mass and 38 kg mass is
Thus the net force on mass 38.0 kg is 
Disclaimer: I just answered this, here is the answer again!
*Used copy paste from my own answer as it is a repeated question, no copied work*
3. A
The relation between V and I at constant R is;V=IR, so it is a direct linear relation.
4. A
This is another direct linear relation as P=IV.
5. D
The relation between P, R, and V is P=, so P is inversely proportional to R.
6.B
The relation between P,I, and R is , so P is directly proportional to the square of I.
Please note that y:x relations are always straight lines while relations are parabolic lines.
Hope this helps!
Answer:
A : the handle will be hot because metal is a good conductor of heat
Explanation:
B The handle will be slippery because metal is slippery when heated. - there is no evidence of this literally anywhere lol
C The handle will be soft because the metal in cooking pans is easily melted. - cast irons melting degree is 1204°C, so unless your cooking lava or something the handle is not gonna melt
D The handle will be freezing cold because metal turns heat to cold. - No, because the containments of the pot are hot not cold, and metal conducts heat
