Answer:
D (density) = M (mass) / V (volume)
M = D * V = 5 g / cm^3 * 1000 cm^3 = 5000 g
The mass of the block of granite is 5000 grams.
We know that density is defined as mass divided by volume. So, we can write the following equation:
Density = Mass / Volume
We are given that the density of the granite is 5 g/cm³ and the volume is 1000 cm³.
We can plug these values into the equation to solve for the mass:
5 g/cm³ = Mass / 1000 cm³
Mass = (5 g/cm³)(1000 cm³)
Mass = 5000 grams
1 cm³ of granite has a mass of 5 grams. So, a block of granite with a volume of 1000 cm³ will have a mass of 5000 grams.

Round 0.010229 to four sig figs
It would be 0.01023.
0.010229 has 5 sig. fig.'s (leading zeros do not count)
So rounding to 4 sig. fig.'s is just a matter of rounding off the last digit, which leaves you with 0.01023.

If Bert the Bat travels eastward at 40 mph with a tailwind of 6 mph, what is his actual speed?
Answer:
36 mph.
Explanation:
Now Albert here is using the wind to his advantage but if say there was no wind then he would not have the 6 mph behind him so we subtract 6 from 40 to get 36. hope this helps :)

What's Centripetal force................
Answer:
a force that acts on a body moving in a circular path and is directed towards the centre around which the body is moving.
Answer:
A centripetal force is a force that makes a body follow a curved path. Its direction is always orthogonal to the motion of the body and towards the fixed point of the instantaneous center of curvature of the path.

Which statement is true?
A. When a gas condenses to a liquid, it absorbs energy.
B. When water boils, it releases energy.
C. When ice melts, it absorbs energy.
D. When water freezes, it absorbs energy.
Explanation:
The correct answer is option B

1. the distance travelled.
2. the velocity after 2 seconds.
e. A stone is thrown vertically upward with the velocity of 25 m/s. How longo it take to reach the maximum height? Also calculate the height.
with process please
Answer:
a)20 m,2s
Explanation:
Given
Initial velocity=20 m /sec
g=10 m/s square
v =0m/s
h =?
t =?
now,
v = U +gt
=v=20 +10t
Or,10t=20
Or,t=20
10
therfore ,2 s.
Again,
h=ut -1 gt square
2
Or, h=20×2-1×10(2)square (multiply and cut )2×5 =10
; 2
Or,40-5×4
therefore , 20m
