Answer:
N = 1364 N
Explanation:
given data
accelerate upward = 5.70 m/s²
mass = 88.0 kg
solution
normal force is in upward direction so, weight of the student in downward direction and acceleration is in upward direction so formula is express as
N - mg = ma ...........................1
N = m × (g+a)
put here value
N = 88.0 × (9.8 + 5.70)
N = 1364 N
The ball has travelled a total distance of 18 feet after dropping and rebounding.
After being dropped for the first time, the ball will rebound to a height of 3 feet as it returns to half its original height. The geometric series formed by the total distance travelled while falling and rebounding has a common ratio,
r = 0.5
6 ft + 3 ft = 9 ft will be the first term in the series
For the sum formula S = ,
substitute a = 9 and r = 0.5 to get the ball's total distance travelled.
S =
S =
S = 18
The ball has therefore travelled a total of 18 feet.

I believe he made a theory that light was electromagnetic radiation
Answer:
towards left
Explanation:
As we know that there is no external force on the system of two cart so total momentum of the system is conserved
so we will say
now plug in all data into the above equation
here we assumed that left direction of motion is negative while right direction is positive
so we can solve it for speed v now
Answer:
Biodiversity.
Explanation:
The number of different species in a particular area is known as biodiversity. Blue whales, plants, different kind of animals, and micro-organism living in an ocean is the example of biodiversity. In biodiversity each specie has its own role. For example, if a biodiversity has large number of plants (species), it will have many type of crops.
