A 5.0 kg object moving at 5.0 m/s. KE = mv2 times 1/2
steposvetlana [31]

Answer: KE = 62.5J

Explanation:

Given that

Mass of object = 5kg

kinetic energy KE = ?

velocity of object = 5m/s

Since kinetic energy is the energy possessed by a moving object, and it depends on the mass (m) of the object and the velocity (v) by which it moves. Therefore, the object has kinetic energy.

i.e K.E = 1/2mv^2

KE = 1/2 x 5kg x (5m/s)^2

KE = 0.5 x 5 x 25

KE = 62.5J

Thus, the object has 62.5 joules of kinetic energy.

Why should it take significantly more energy to move a beam of alpha particles than a beam of beta minus (β–) particles?
a_sh-v [17]
An 'alpha particle' is the same thing as the nucleus of a helium atom ... 
a little bundle made of 2 protons and 2 neutrons.

A 'beta' particle is an electron.

The mass of an alpha particle is more than 7,000 times the mass of 
an electron, so it certainly takes more energy to get it moving.

A friend has written to you informing you that she/he giving him/her the name of some place in nepal
sleet_krkn [62]

Answer:

The answer is below

Explanation:

Dear Friend,

I received your letter a few days back. And because I was busy with work, I couldn't write a reply to you immediately. However, here is my well-detailed reply to your request. I hope you find it satisfactory. I am excited to learn that you wish to go on a tour to Nepal. For the advice, here is my suggestion for some places for you to visit.

1. Kathmandu: this is the capital of Nepal. It also doubles as the capital city. The atmosphere there is electric. The streets are wide and there are old monumental buildings there.

2. Bhaktapur: here you find interesting things around. It is the third-largest royal city. Durbar square is a nice place to visit.

3. Pokhara: this place has the largest population and the city is cleaner compared to most other big cities around. It has wonderful places to relax. And if you enjoy hiking this is the place for you.

4. Chitwan National Park: I know you love watching wildlife. So this is a must for you to visit. You get to see amazing animals such as rhinos, Bengal tigers, leopards, etc.

However, due to space and for me not to bore you, here are other honorable mentions

Trekking in the Langtang region, Swayambhunath, known as Monkey Temple. You should also consider the Everest & the Trek to Base Camp.

I hope you will enjoy your stay to the fullest. Don't forget to send me details of your tour after your visit.

I love you, friend.

Yours sincerely,

MyName
