The first American to orbit the earth was:Frank Borman
Buzz Aldrin
Neil Armstrong
John Glenn

Answers

John Glenn is the first American to orbit the Earth.

♡♡Hope I helped!!! :)♡♡

Yes, John Glenn was the first to orbit the earth but the question I read was who WALKED ON THE MOON.....the answer to who was the FIRST to walk on the moon... is  Neil Armstrong but Buzz Aldrin also walked and was there with Armstrong but wasn't the first.  You have to be careful about the astronaut 'firsts'.  Alan Shepherd was the first in space....John Glenn was the first to orbit the earth....Edward White was the first to 'walk in space' and Neil Armstrong was the first man to walk on the moon. Also remember that all of these were American Astronaut firsts.  The Russians actually put up the first man in space.  Yuri Gagarin was the first man.  Buzz Aldrin landed and walked on the moon also.

.Please explain to me how to find the momentum

Answers

Answer:

momentum = mass x velocity

Explanation:

So ultimately, find the mass of the object (be careful since this is not the same as weight. Weight is your gravitational pull to the earth. This means that your weight different amounts on different planets. But mass stays the same on all planets, it's what most people call their weight.) and then find the velocity (2 meters/second north, etc.)

Now you can apply this to your problem

an electron is held at a distance from a stationary, positively charged object . If the electron is released , what energy change will take place?

Answers

Answer:

Electrostatic potential energy will convert into kinetic energy

Explanation:

When electron is released from rest at some distance from positive charge then due to electrostatic attraction force these two charges will attract each other.

Now in the form of energy we can say that

electrostatic potential energy = (kq_1q_2)/(r)

now as the two charges comes closer to each other then the electrostatic potential energy will decrease and hence this energy will convert into kinetic energy of two charges

so we can say

(kq_1q_2)/(r_2) - (kq_1q_2)/(r_1) = (1)/(2)mv^2
Electric potential energy will be transformed into kinetic energy.

If the abosolute of a gas is 600 k, the temperature in degrees Celsius is

Answers


Absolute Zero (Zero Kelvin) = -273.15° Celsius.

Zero° Celsius = 273.15 Kelvin .

600 K  =  (600 - 273.15°) = 326.85°C.

In a closed system, glider A with a mass of 0.40 kg and a speed of 2.00 m/s collides with glider B at rest with a mass of 1.20 kg. The two interlock and move off. What speed are they moving at?

Answers

The speed are they moving at will be 0.5 m/sec.Law of conservation of momentum is applied.

What is the law of conservation of momentum?

According to the law of conservation of momentum, the momentum of the body before the collision is always equal to the momentum of the body after the collision.

The given data in the problem is;

(m₁) is the mass of 1st gilder=  0.40 kg

(u₁) is the initial velocity = 2 m/s

(m₂) is the mass of 2nd gilder = 1.20 kg

(u₂) is the initial velocity of 2nd gilder = 0 m/s

(v) is the velocity after collision =.?  

According to the law of conservation of momentum;

Momentum before collision =Momentum after collision

\rm m_1u_1 + m_2u_2 = v(m_1 + m_2)\n\n(0.40* 0.25) + (1.2 * 0) = v * (0.40+1.20) \n\n 125 + 0 = v * (1250) * 125 \n\n \rm v= (0.8)/(1.6) \n\n \rm v= 0.5 \ m/sec

Hence, the speed are they moving at will be 0.5 m/sec

#SPJ2
Conservation of momentum.
m1*u1 + m2*u2 =m1*v1 + m2*v2
here u2=0 body at rest, v1=v2=v both interlock and move together
0..4*2+1.2*0 = 0.4*v+1.2*v
v= 0.8/1.6 = 0.5 m/sec

TRUE OR FALSE : Boyle’s law states that, as the pressure of a gas increases, the volume decreases.

Answers


At first glance, this statement seems to be true.  But after about a
microsecond of further consideration, one realizes that the statement
would actually set Boyle spinning in his grave, and is false.

Boyle's law states that there is a firm relationship among the pressure,
temperature, and volume of an ideal gas, and that you can't say anything
about how any two of these quantities depend on each other, unless you
also say what's happening to the third one at the same time.

As the pressure of an ideal gas increases, the volume will decrease in
direct proportion to the volume, IF THE TEMPERATURE OF THE GAS
REMAINS CONSTANT.

If you wanted to, you could increase the pressure AND the volume of an
ideal gas both at the same time.  You would just need to warm it enough
while you squeeze it.
