Explanation:
The runner was 8.6km away from the finish line when the bird starts flying.
Therefore it takes the bird 8.6/14.4 = 0.60 hours for the bird to fly to the finish line.
In that 0.60 hours, the runner would have ran an extra 3.6km/h * 0.6h = 2.16km.
Now, the runner and the bird are flying towards each other. The distance between them is 8.6 - 2.16 = 6.44km and their combined speed is 18.0km.
Hence, they will meet in 6.44/18.0 = 0.36 hours.
Overall, the bird flew for 0.60 + 0.36 = 0.96 hours, and flew 14.4km/h * 0.96h = 13.8km.
Answer:
Its mechanical energy is the same.
Explanation:
If forces are only conservative, the mechanical energy will be the same.
It can be different if energy get transformed in another kind of energy like elastic energy for example, although the amount of energy is always the same.
If we just have mechanical energy not geting transformed we have:
Em=K+U
Em: Mechanical energy
K: Kinetic energý
U: Potential energy
Then if Kinetic energy decreases 10J, Potential energy will grow up 10J to keep the same amount of mechanical energy.
Answer: 4.5 V
Explanation:
Given
The voltage of each cell is 1.5 V
If they are connected end to end their potential added to give a higher potential i.e. 1.5+1.5+1.5=4.5 V
Gravity pulls the moon towards the earth.
Sport-type motorcycles typically feature a higher than average power-to-weight ratio.
- Sport-style motorcycles often have a power-to-weight ratio that is above average.
- Fuel refers to opening the fuel supply valve, if available.
- Set the choke and squeeze the clutch lever together is referred known as "choke and clutch."
- Even though some motorcycles lack a choke, the choke should be ON for a cold engine.
What is scrambler motorcycle?
- Scrambler motorbikes, also referred to as dirt bikes, have special features designed for off-road activities and sports.
- Off-road, to be clear, is any route that isn't paved or that follows a set pattern.
- Scrambler bicycles feature relatively straightforward designs, long suspensions, and high ground clearance.
