Answer:
- A: r
- B: f
- A: r
Step-by-step explanation:
1. Greater density means the sphere has more mass in the same volume. The volume of water that must be displaced to equal that increased mass must be increased, causing the water level to rise.
__
2. Less mass means less water must be displaced to equal the mass of the new sphere, causing the water level to fall.
__
3. More mass is the same as higher density (see 1). The water level will rise.
Answer:
4909 m/hr
6000 m/hr
Step-by-step explanation:
Last Year :
Distance = 300 m
Time = 3 2/3 minutes
Speed per hour = distance / time
Time in hour = 11/3 ÷ 60 = 0.0611111 hour
300 / 0.0611111 = 4909.0918 m /hr
= 4909 m/hr
This year :
Distance = 200 m
Time = 3 minutes
Speed per hour = distance / time
Time in hour = 3 ÷ 60 = 0.0333333 hour
200 / 0.0333333 = 6000.0060 m /hr
= 6000 m/hr
Y = -x + 3 .… m = -1
y = 2x – 6 .… m = 2
Tan Ø = | m2 – m1 / 1 + m2m1 |
Tan Ø = | 2 – -1 / 1 + (2 x -1) |
Tan Ø = | 3 / -1 |
Tan Ø = | -3 |
Tan Ø = 3
Ø = tan^-1 ( 3 )
Ø = 71.5°
