Answer:
<em>4.67 N of force are required</em>
Explanation:
The second Newton's law states the net force exerted on a body of mass m that has an acceleration a, is given by:
F=m.a
On the other hand, the kinematics equations relate the acceleration with the change of speed over time, expressed as:
We are given the initial speed of vo=4 m/s on a mass of m=3.5 Kg, the final speed of vf=8 m/s which took t=3 seconds.
The acceleration is:
Thus, the force is:
4.67 N of force are required
Answer:
The angle is 1.33°.
Explanation:
Given that,
Distance 
Wavelength = 650 nm
Number of fringe = 3
We need to calculate the angle
Using formula of angle for brightness
Where, d = distance
=wavelength
m = number of fringe
Put the value into the formula
Hence, The angle is 1.33°.
Answer:
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies
A hypothesis is when a scientific method gets the same results
