Answer:
The blood vessels dat carry blood away from the heart are non as arteries, while those dat carry blood back to the heart are veins.
Explanation:
The ARTERIES are major blood vessels connected to your heart.
Answer:
decreases
Explanation:
on each collision, the electrons that make up x-rays get absorbed.
Answer:
<h3>3.33m/s</h3>
Explanation:
Using the law of conservation of momentum
m1u1 + m2u2 = (m1+m2)v
m1 and m2 are the masses of the object
u1 and u2 are the velocities
v is the final velocity
Given
m1 = 50g
u1 = 10m/s
m2 = 100g
u2 = 0m/s (stationary ball)
Required
Common velocity v
Substitute
50(10) + 100(0) = (50+100)v
500 = 150v
v = 500/150
v = 3.33m/s
Hence the velocity of each ball immediately after the collision is 3.33m/s
Magnetic fields and electric fields are similar on the basis of the forces and its application.
<h3>What is an electric field?</h3>
An electric field is an electric property that is connected with any location in space where a charge exists in any form. The electric force per unit charge is another term for an electric field.
Magnetic and electric fields have certain similarities, are as follows;
1. Both the electric force and magnetic forces are the non-contact forces.
2. Both acts between the two entity having certain mass.
3. Both have their respective ranges.
Hence, magnetic fields and electric fields are similar on the basis of the forces and its application.

<u>Answer:</u>
<em>The outside edge of a spinning compact disc moves with a higher velocity than the inner track of the disc.</em>
<u>Explanation:</u>
Here the compact disc undergoes rotational motion about a fixed axis which is its centre in this case. The particles in rotational motion have angular velocity which is given by the equation
ω = ∅/t
Where θ is the angular displacement and t is the time.
The transnational speed of a particle which is in circular motion is given by the equation
v = rω
r is the distance of the point from the rotation centre
The transnational speed of the particles is merely determined by their distance from the centre in this case. It is due to the equality of angular velocity of all the points.
The distance of the outer edge of the compact disc from its rotational centre is larger than the distance of inner edge from the rotational centre. Thus the farther edge of a spinning disc moves faster than the nearer edge.
