Answer:

22m/s

Explanation:

Given parameters:

Time  = 5s

Acceleration  = 4m/s²

Initial velocity  = 2m/s

Unknown

Final speed  = ?

Solution:

To solve this problem, we use the expression below;

         v = u + at

v is the final speed

u is the initial speed

a is the acceleration

t is the time taken

 So, insert the parameters and solve;

         v  = 2 + 4 x 5  = 22m/s

tamaranim1 [39]

Answer: b) Less dense

Explanation:

Differences in density is one reason objects float or sink.

An object more dense than the fluid in which it is immersed will sink, while objects less dense than the fluid in which it is immersed will float to the surface.

But objects floats at constant level if the density is equal to the density of the fluid in which it is immersed; it neither rises nor sinks in the fluid in this case.

How well did tossing the pennies simulate half lives?
SSSSS [86.1K]
Its a 50% chance that approx 1/2 of the pennies will land on tails. The next toss will result the same. and so on and so on. showing how a reaction would slowly eliminate 1/2 of the remaining lives per reaction, until nothing is left. I think it is a good stimulation.
