Answer:
a. 6.04 m/s^2 (3 sig. fig.) b. T = 30.2 N
Explanation:
a) Assume that the acceleration due to gravity is 9.81 m/s^2 downwards
8x9.81 = (5+8)a
a = 6.04 m/s^2 (3 sig. fig.)
b) Using the results from (a)
T = 5(6.04)
T = 30.2 N
Answer:
Explanation:
Given
angle through which ball is launched
Range of ball=50 m
Range of projectile is 
u=22.136 m/s
If ball is thrown straight upward
s=25 m
(b)For Projectile time of flight is
t=3.19 s
<span>What you need to do while answering this questions, is ask yourself what has cells - only if a thing has cells can you see those cells under a microscope. Objects of animal and plant origin have cells, so blood, plant and cork (made of tree bark) can have cells, and a box too, if it's made of wood. So we can''t exclude any answers based on this. We must then know the story of Robert Hook - and it was in fact a cork. He did this discovery around 1655. At the time his main interest was the microscope rather than the cork, and he used to cork to demonstrate the function of the microscope. The correct answer is CORK.</span>
The answer is C sorry if it’s wrong
