Explain it if u know please ​
Rudik [331]

Answer: B

Explanation: The straight line shows the theoretical average of the actual velocity  and the curved line show that it is less than the average velocity of the object within 6 seconds.

straight line:

3. 3,80

6. 6,160

curved line:

  1. 1,2
  2. 2,17
  3. 3,32
  4. 4,60
  5. 5,100
  6. 6,160

A.K.A.-- the only place where the straight line and the curved line meet at is only at coordinate 6,160.

An electron and a proton are initially very far apart (effectively an infinite distance apart). They are then brought together t
Lina20 [59]

Answer:

dU=-4.36*10^{-18}J

Explanation:

From the question we are told that:

Average distance d_{avg} =5.29*10^{-11}m

Generally the equation for change in electric potential energy is mathematically given by

dU=u_f-U_1

Where

U_1=0 Because of initial lengthy distance apart

And

U_f=\frac{kq_eq_p}{d}

U_f=\frac{9*10^9*1.6*10^{-19}*-1.6*10^{-19}}{5.29*10^{-11}}

U_f=-4.36*10^{-18}J

Therefore

dU=u_f-U_1

dU=-4.36*10^{-18}J-0

dU=-4.36*10^{-18}J

A 16 lb block rests on a horizontal frictionless surface. A cord attached to the block, running horizontally, passes over a pull
quester [9]

Answer:

I = 6.2161900319309  slug-feet^2[/tex]

Explanation:

The moment of inertia of an object may simply be stated as a measure of how difficult it is to start it spinning, or to alter an object's spinning motion

The moment of inertia of an object is given by the expression

I=mr^{2}

but in this case we are talking about the moment of inertia of a circular disk, the expression is a bit different

I=[tex]\frac{1}{2}mr^{2}[/tex]

inputting the values given in the expression above

I=\frac{1}{2}(16)5^{2}

moment of inertia  = 200 lb

the expected outcome should be in slug feet squared

1 slug-feet squared = 32.1740488782426

therefore we need to divide our answer by this value

so

= \frac{200}{32.1740488782426} \\= 6.2161900319309  slug-feet^2
