Answer:
P = 350 [Pa]
Explanation:
The pressure is calculated by knowing the force and area. By means of the following formula can be calculated by means of the following equation.
Units of 1 [Pa] = 1 [N/m²]
P = F/A
where:
P = pressure [Pa]
F = force = 560 [N]
A = area = 1.6 [m²]
P = 560/1.6
P = 350 [Pa]
Answer:
R' = R/4
Explanation:
The resistance of a metal rod is R. It is given by the relation as follows :

Where
l is the length and A is the area of cross-section

If both its length and its diameter are quadrupled, it means,
l' = 4l
and d'= 4d
It means,

Let new resistance be R'. So,

So, the correct option is (B) "R/4".
- Initial velocity=u=10m/s
- Final velocity=v
- Acceleration=a=4m/s^2
- Distance=s=60m
According to third equation of kinematics





Answer:
I am going to say A
Explanation:
solids are normally close and tightly packed molecules and while ice is in solid form,so is it.
Let me know if i was right! Hope this helps! :)
The density of the nugget is
and is made of gold
Explanation:
The density of an object can be calculated as

where
d is the density
m is the mass
V is the volume of the object
We have to note that density of an object actually depends on the material the object is made of (therefore, two objects made of the same material can have different mass and different volume, but they have same density).
For the nugget in this problem, we have:
mass: m = 38 g
volume: 
So, its density is

And by looking at the table, we see that this value corresponds approximately to the density of gold, so the nugget is made of gold.
