Answer:
The density of the sun is 4434kg/m³
This was found by dividing the mass (1.989 ×10³⁰kg) by the volume (4.486×10²⁶ m³) which was calculated using V = 4/3×pi ×r³
Explanation:
See attachment below.
Answer:
The taken is
Explanation:
Frm the question we are told that
The speed of car A is
The speed of car B is
The distance of car B from A is
The acceleration of car A is
For A to overtake B
The distance traveled by car B = The distance traveled by car A - 300m
Now the this distance traveled by car B before it is overtaken by A is
Where is the time taken by car B
Now this can also be represented as using equation of motion as
Now substituting values
Equating the both d
substituting values
Solving this using quadratic formula we have that
The red filter changes the color of the white light. For example, if you have a white light, and then cover it with a green filter, the light is now green.
Answer:
= Approximately 6
Explanation:
<u>What we need to know:</u>
1. Given that this is a parallel circuit, each pathway will receive the full voltage from the source. Therefore, each pathway will receive 17V.
2. The current (I) stays the same for all loads in series. Therefore, I2 and I3 are equal since they are connected in series.
3. Ohm's law states that Voltage = Current × Resistance (V=IR)(I=V/R)(R=V/I)
<u>1) Calculate the current for the path containing R2 and R3</u>
Because the current running through this path is A, then I2 is A.
<u>2) Use Ohm's Law by plugging in I2 and R2</u>
(approximate)
Therefore, V2 is approximately 6V.
I hope this helps!
A red ladybug appears red in white light, red in red light, and black in blue light. Those would be the proper selections you'd need.
