An airplane flew from San Francisco to Washington, D.C. Approximately

Physics
1 answer:
Arada [10]3 years ago
5 0

Answer:

The solution is given below:

Explanation:

The computation of the speed is shown below

As we know that

Speed = distance ÷ time

where

distance is 2000 km

And, the time is 2.5 hours

SO, the speed is

= 2,000 ÷ 2.5

= 800 km/h

Now the distance would be the same i.e. 2,000 km

but the time is 2 hours

So, the speed is

= 2,000 km ÷ 2 hours

= 1,000 km/hr

The direction should be opposite to the first airplane

You're using a wedge to split a log. you are hitting the wedge with a large hammer to drive it into the log. it takes a force of
KIM [24]
The work performed on an object is the force multiplied by the distance it is moved, provided the movement is parallel to the force.  Since that is the case here, we can get the work by W=Fd=1900N x 0.23m = 437J.  This energy is used to split the wood.

Calculate the average value of an AC signal with a peak amplitude of 10V and a frequency of 10 kHz.
Solnce55 [7]

Answer:

V(average)=6.37 V

Explanation:

Given Data

Peak Voltage=10V

Frequency=10 kHZ

To Find

Average Voltage

Solution

For this first we need to find Voltage peak to peak

So

Voltage (peak to peak)= 2× voltage peak

Voltage (peak to peak)= 2×10

Voltage (peak to peak)= 20 V

Now from Voltage (peak to peak) formula we can find the Average Voltage

So

Voltage (peak to peak)=π×V(average)

V(average)=Voltage (peak to peak)/π

V(average)=20/3.14

V(average)=6.37 V
