DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms.DNA testing relies on comparing fragments of DNA (called “genetic loci” or simply “loci”) between an alleged parent and a child. A child receives one half of his DNA from the mother and the other one from the father moreover, the process is more or less random.

Two water balloons of mass 0.35 kg collide and bounce off of each other
sladkih [1.3K]

Answer:

Option D

2 m/s East

Explanation:

From the law of conservation of momentum, the sum of initial momentum equals the sum of final momentum

Momentum, p=mv where m is the mass and v is the velocity

Since the masses are the same then

m(u_1+u_2)=m(v_1+v_2)  

Therefore

u_1+u_2=v_1+v_2

where v_1 and v_2 are final velocities of objects while u_1 and u_2 are the initial velocities respectively

Taking East direction as positive then West as negative and by substitution

2.5+-2.25=v_1-1.75

Therefore

v_1=2 m/s hence East since it's positive

A drone flies 8 m/s due East with respects to the wind. The wind is blowing 6 m/s due North with respects to the ground. What is
Shalnov [3]

Answer:

v=10 m/s

Explanation:

Given that,

Speed of a drone is 8 m/s due East with respects to the wind

Speed of a drone 6 m/s due North with respect to the ground.

We need to find the speed of the drone with respect to the ground. Let v is the speed. It is given by the resultant of two speeds.

v=\sqrt{8^2+6^2} \\\\v=10\ m/s

So, the speed of the drone with respect to the ground is 10 m/s.
