courts have many properties including Mass electric charge and color their Mass tells you something about how much matter they are made of or how heavy they would be if you could wear them up charm and top quarks have a positive 2/3 charge
Astronauts brought back 500 lbs rock samples from the moon. They brought back 227 kilograms of sample.
An Astronaut is a person who has been educated, prepared, and put into space as part of a human spaceflight mission to serve as a commander or crew member. The word is frequently used to refer to scientists as well as professional space explorers, while being usually reserved for all of those who travel into space on a daily basis.
According to the given question, Astronaut bought back 550 lbs sample,
We know that,
2.20lbs = 1 kg.
1 lbs = 1/2.20 kg
1 lbs = 0.45 kg
Hence, 500 lbs equals 227kgs according to the given relation.
So, Astronauts brought back 227 kilograms of sample.

The correct answer is “C” ultrasound. Hope this helps!
Answer:
(a) 6.283 Wb (b) 69.11 Wb (c) I = 0.628 A
Explanation:
Given that,
The diameter of the loop, d = 40 cm
Radius, r = 20 cm
Initial magnetic field, B = 5 mT
Final magnetic field, B' = 55 mT
Initial magnetic flux,
Final magnetic flux,
Due to change in magnetic field an emf will be generated in the loop. It is given by :
Let I be the current in the loop. We can find it using Ohm's law such that,
Hence, this is the required solution.
Answer:
A) 0.50 mV
Explanation:
In this problem, we can think the wings of the bird as a metal rod moving across a magnetic field. So, and emf will be induced into the wings of the bird, according to the formula:
where
is the strength of the magnetic field
v = 13 m/s is the speed of the bird
L = 1.2 m is the wingspan of the bird
is the angle between the direction of motion and the direction of the magnetic field
Substituting numbers into the formula, we find
