He tells you (a speed) per (a time). That's a rate of acceleration .
Let's find out what the acceleration is:
(60 mile/hour) / (6 seconds)
= 10 miles/hour-second
Weird units. Let's convert to something easier.
(10 mi/hr-sec) x (5280 ft/mi) x (1 hr / 3600 sec)
= 14-2/3 ft/sec² = about 0.46 'G'
about 4.47 meter/s²
Answer:
About two kilometers away
Explanation:
Given:
The time gap between the light and sound to travel to the house,
<em>Since the clouds are formed in the troposphere region of the atmosphere which extends from 8 kilometers to 12 kilometers above the earth-surface and the velocity of light is 300000 kilometers per second so it is visible almost instantly, hence we neglect the time taken by the light to travel to the house from the clouds.</em>
<u>∴Distance between the lightning-strike and the house:</u>
we have the speed of sound as:
So,
Explanation:
Scratch the mineral with the blade of a pocket knife. Rub off any loose powder to see if the mineral has been scratched.
Answer:
1. Golf ball is in the range of only particulate detectable range
2, alpha partcle is in ultraviolet range of wavelength
3.bullet is in xray range of wavelength
All in the EMW spectrum
Explanation:
Both graphs show plotted points forming a curved line. Curved lines have changing slope; they may start with a very small slope and begin curving sharply (either upwards or downwards) towards a large slope. In either case, the curved line of changing slope is a sign of accelerated motion (i.e., changing velocity).
