Answer:
The speed of the wind is 70.7 units.
Explanation:
The velocity of the wind is equal to plane's velocity before the wind minus its velocity after the wind:
Now, the speed of the wind is the magnitude of :
which is the speed of the wind.
<em>P.S: No units are given for speed because no units were provided in the question.</em>
The only statement which is true is:
<span>In a series circuit, the resistors do not share the current.
In fact, when resistors are put in series, the current I crosses all the resistors with same intensity, and so the resistors are all crossed by the same value of the current.</span>
1. D: the ability to cause a change or do work
The others dont make sense for energy.
2. C: Lamp
A lamp uses the electric current to light up a room, or area.
3. B: foil will bend away
The same charges repel each other that is why a magnet is repelled by the same pole of another magnet.
4. A: Sound
You can’t hear light or any of the other options.
5. A: gravity
Gravity is a force of nature that pulls on everything.
6. C: static electricity
The opposite charges stick to each other, a battery again is an example of this.
7. B: a copper nail
Metal is one of the best electric conductors.
8. C: closed circuit
This is because if a circuit is closed the electricity flows through perfectly but for example an open one would not work or it would leak energy.
Hope this helps
Answer:
Tread design on car B would yield a larger coefficient of static friction between the tires and the road
Explanation:
The car model using the coefficient of static friction doesn't work well with tires. A higher coefficient of static friction would require more force to cause a loss of attraction.
The static frictional force helps to keep the unbanked horizontal turn. This means that the frictional force is the centripetal force.
The tread design of car B ensures that the centripetal force is enough to negotiate the turn. On the other hand, the tread design of car A does not provide the necessary centripetal force, hence car A is unable to negotiate the turn.
Therefore, tread design on car B would yield a larger coefficient of static friction between the tires and the road.
I want to examine the surface of a planet that is covered by a thick atmosphere (which includes oxygen and contains a very thick layer of water clouds that never clears). What wavelength of electromagnetic radiation would I be smartest to use: radar waves.
Radars send out electromagnetic waves much like wireless computer networks and cell phones. The signals are despatched out as short pulses which can be reflected by objects of their route, in part reflecting returned to the radar.
The radio waves travel outward from the antenna at the velocity of light (186,000 miles or three hundred,000 km in keeping with the second) and keep going until they hit something.
Then some of them bounce back in the direction of the antenna in a beam of contemplated radio waves also visiting at the speed of light. the speed of the waves is crucially vital.
