C) A bullet having a mass of 10 g andmoving with a speed of 1.5 m/s,penetrates a thick wooden plank ofmass 900 g. The plank was initiallyat rest. The bullet gets embedded inthe plank and both move together.Determine their velocity.(Ans: 0.15 m/s)​

Answer»

Answer:

GIVEN :  

mass of bullet= 10G= 0.01kg

velocity of bullet= 1.5m/s

mass of plank= 90g=0.09kg

Total momentum before collision=mass of plank x velocity

=0.01x1.5+0.09x0=0.015 kgm/s

Total momentum after collision=(mass of bullet +mass of plank )x velocity

=0.1 kg x V=0.1 V kgm/s

According to law of CONSERVATION of momentum,

Total momentum before collision=Total momentum after collision

0.015kg m/s =0.1 v kg m/s

Thus,velocity ACQUIRED by the plank and the bullet = 0.15m/s

5.

B) An object of mass 16 kg is movingwith an acceleration of 3 m/s2Calculate the applied force. If thesame force is applied on an object ofmass 24 kg, how much will be theacceleration? (Ans: 48 N, 2 m/s2)solve this example. and explain it ​

Answer»

Answer:

48 N, 2m/s²

Explanation:

GIVEN:

MASS (m) = 16kg

Acceleration (a) = 3m/s²

We KNOW that,

⇒ F = ma

∴ F = 16 * 3

      =  48N

Now we have,

Mass (m₂) = 24 kg

⇒ F = ma

⇒ 48 = 24 *a

∴ a = 48/24

     = 2m/s²

I do hope that this HELPS you, mate!

Imagine walking into a meeting room. You shake hands with colleagues, then everyone sits down. Within seconds they all start SNIFFING their palms, picking up clues about you from the chemical traces left over from the handshakes.

Sniffing palms after a handshake, usually within 30 seconds of the interaction, would likely help people learn about someone’s HEALTH and genetic compatibility, according to a 2015 study by researchers in Israel. Sniffing can also offer information on people’s emotional state, such as if they are happy, sad or fearful. The smeller gleans these emotions subconsciously, of course.

For decades, scientists believed humans were not very good at detecting and identifying odors. Our animal ancestors used their NOSES way more than we do in modern society, says JESSICA Freiherr, a neuroscientist at RWTH Aachen University, in Germany, and the author of several studies on the human sense of smell. “We are disconnected from our noses,” she says. “We need them much less in everyday life. And our vision overrides the sense of smell in a lot of situations
