vagabundo [1.1K]3 years ago
7 0

Answer:

112.5 N

Explanation:

50 = GMm/r^2

Let F be the new force of attraction

F/50 = ( G(3M)(3m)/(2r)^2 ) / (GMm/r^2)

[Elimiating G,M,m,r]

F = 112.5 N

What is the average velocity of Runner C for the first 15 seconds? Question 5 options: 1.3 m/s -2.7 m/s -1.3 m/s 2.7 m/s
kipiarov [429]

Answer:

Average velocity (v) of an object is equal to its final velocity (v) plus initial velocity (u), divided by two.

v¯¯¯=(v+u)2

Where:

v¯¯¯ = average velocity

v = final velocity

u = initial velocity

The average velocity calculator solves for the average velocity using the same method as finding the average of any two numbers. The sum of the initial and final velocity is divided by 2 to find the average. The average velocity calculator uses the formula that shows the average velocity (v) equals the sum of the final velocity (v) and the initial velocity (u), divided by 2.

Which answer is a scientifically accurate description of velocity?
Tcecarenko [31]

The boat traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

Explanation:

A boat traveling from the dock northward to a 200m mark in the bay in less than 5minutes giving the passengers several more hours to fish is a typical and best example of velocity description.

Velocity is the displacement of a body divided by the time taken.

 Velocity = \frac{displacement}{time}

Displacement is the distance covered in a specific direction. Time is duration of the travel.

Velocity is a vector quantity that has both magnitude and direction. This implies that the value of velocity is recorded with a directional attribute.

We can say velocity is the speed of a body in a given direction

Only the last option gives the displacement of the body and the duration it traveled.

Two electrodes connected to a 9.0 v battery are charged to ±45 nc. What is the capacitance of the electrode?
mart [117]

Answer:

5\cdot 10^{-9} F

Explanation:

The capacitance of the electrode is given by:

C=\frac{Q}{V}

where

C is the capacitance

Q is the charge on the electrode

V is the potential difference

In this problem, we have

Q=45 nC=45\cdot 10^{-9} C

V = 9.0 V

Substituting into the equation, we find

C=\frac{45\cdot 10^{-9}C}{9.0 V}=5\cdot 10^{-9} F (5 nF)
