They have a uniform luminosity and are similar to the bulge in a spiral galaxy, but with no disk. The stars are old and there is no gas present. Ellipticals are usually found in the high density field, at the centre of clusters.
Answer:
Boy has the greater linear velocity.
Explanation:
The liner velocity in a rotatory system is defined as:
v = ω×r
where,
v is the liner velocity
ω is the angular velocity
r is the radius.
The boy is near the edge and the girl is closer to the center. The scenario is shown in the image below.
As, mentioned in question, they are turning out at a constant rate, so the angular velocities of both the boy and the girl are same.
<u>From the above inference, it can be concluded that now the linear velocity only depends on the radius of the disc. The linear velocity is directly proportional to the distance from the center.</u>
Thus, the greater the distance from the center, the greater the value of liner velocity.
<u>From the question also and from the image also the distance of the boy from the center is greater than the distance of the girl from the center. </u><u>That's why boy has greater linear velocity. </u>
Answer:
Option B) C and D
Explanation:
The amount of charge passing through a resistor each second corresponds to the definition of current, so the problem is asking "which resistors have the same amount of current".
Let's keep in mind that:
- When two resistors are in series (=they are connected into the same branch of the circuit), the current flowing through each resistor is the same
- When two resistors are in parallel (=they are connected into different branches), the potential difference across each resistor is the same
Looking at the previous definitions, we have to find the two resistors in the circuit that are connected in series. We see that resistors C and D are in the same branch, so they are in series: therefore, the current flowing through resistor C and D is the same.
Answer:
It seems that you have missed the necessary options for us to answer this question, so I had to look for it. Anyway, here is the answer. Samaira needs to rent some tents for an outdoor family reunion in July, so the type of tent for Samaira to rent so that her family members are protected from the heat of the sun is SMOOTH and WHITE TENT. Hope this answer helps.
Positive charge you gave the lines pointing away, negative charge is pointing toward. Don’t have a photo so I can’t fill in the blanks BUT I can tell you the logic
