The cell wall does not transfer genetic materials
Answer:
2.465Ns;1.76N
Explanation:
From Newton's Second Law:
There is a conservation of Momentum hence:
Momentum before the impact equals that after the impact.
Hence.
1. The Impulse is same as the change in Momentum which is;
0.145 ×17 =2.465Ns { note: 145g in kg is 0.145}
2. From Newton's third Law; force is the rate of change of impulse expressed mathematically as;
F = m×v / t
Where m×v is impulse and t is time given.
F = 2.465/ 1.4 = 1.76N
Answer:
a).The ball fall by d=8.75m height
b). The ball is falling at time t=1.63s
Explanation:
The problem have no question to answer however typical questions are:
a).By how much does the ball clear or fall short of clearing the crossbar?
b) Does the ball approach the crossbar while still rising or while falling?
,, ,.
The time to get the distance
a).
Now find the ball's height at this time
b).
Now find the reach maximum height if the football reaches is is maximum height
Solve to t
Answer: The car would move to the right with 150 n of force. the 150 n of force from friction and air resistance slows the car from moving to the right with 300 n of force.
Explanation:
Any form of succession will change the environment. That's why there is succession in the first place. With each stage of succession there will be greater biodiversity that results in a change in abiotic factors like soil composition, shade, humidity, weather, exposure, etc
