A car traveled 1025 km from El Paso to Dallas iin 13.5 hr. What was its average velocity

Physics
1 answer:
JulsSmile [24]3 years ago
5 0
1) 1025km per 13.5hr = 1025km/13.5hr = 75.9 km/hr

2) 400km per 30min = 400km/30min = 13.3 km/min
13.3km/min X (60min per hr) = 13.3km/min(60min/hr) = 800km/hr

3) 45km/hr in 40min = 45km/hr X 40min X (1hr/60min) = 30km.

<span> 4) (30m/s - 10m/s) per 10s = 20m/s/10s = 2ms/s = 2m/s/s = 2m/s^2 </span>

If it requires 7.0 JJ of work to stretch a particular spring by 1.7 cmcm from its equilibrium length, how much more work will be
Lynna [10]

Answer:

Explanation:

First of all, well calculate the spring constant k

K = 2Ei/x^2

Where Ei = initial work required

x = initial stretch length

k = 2×7/0.017^2 = 48443J/m^2

Now work done in stretching it to 5.3cm (1.7 + 3.6) or 0.053m

EF = kx^2/2

48443 × 0.053^2/2 = 68J

Work done in stretching additional 3.6cm is equal to

68J-7J = 61J

Anyone please helps me with this question... I'm stuck..
Zolol [24]
Highest fluid potential energy: answer A
Because the fluid is pushed upwards and potential energy is function of height. Since point A is the highest, there is the highest potential energy.

highest fluid pressure: answer C
This is because it is at the bottom where you have a hydrostatic pressure component

increasing fluid speed: answer B
This is because the section of the pipe is smaller and in order to have the same fluid flow rate the speed must increase

Two spherical balloons are filled with water. The first balloon has a radius of 3 cm, and the second has a radius of 6 cm. How m
Marianna [84]

The volume of water in the larger balloon is 8 times greater than in the smaller balloon

We'll begin by calculating the volume of each balloon.

<h3>For smaller balloon:</h3>
  • Radius (r) = 3 cm
  • Pi (π) = 3.14
  • Volume (V) =?

V = 4/3 πr³

V = 4/3 × 3.14 × 3³

<h3>V = 113.04 cm³</h3>

<h3>For larger balloon:</h3>
  • Radius (r) = 6 cm
  • Pi (π) = 3.14
  • Volume (V) =?

V = 4/3 πr³

V = 4/3 × 3.14 × 6³

<h3>V = 904.32 cm³</h3>

Finally, we shall determine how much greater the larger balloon is to the smaller balloon

  • Volume of smaller balloon = 113.04 cm³
  • Volume of larger balloon = 904.32 cm³
  • Greatness =?

Greatness => large / small

Large / small = 904.32 / 113.04

Large / small = 8

Cross multiply

<h3>Large = 8 × small </h3>

Therefore, the larger balloon is 8 times greater than the smaller balloon.
