How does an electroscope detect negative static electricity

Physics
1 answer:
MA_775_DIABLO [31]2 years ago
5 0
<span> An electroscope that might have a static charge is tested on a metal surface. From there, the charges move to the metal and straight to the foil leaves. If they repel, or move away from each other, that means they have identical charges. This applies for both positive and negative static electricity.

A train moving at a constant speed on a surface inclined upward at 10.0° with the horizontal travels a distance of 400 meters in
Amiraneli [1.4K]
If the velocity of the train is v=s/t, where s is the distance and t is time, then v=400/5=80m/s. To get the vertical component of the velocity we need to multiply the velocity v with a sin(α): Vv=v*sin(α), where Vv is the vertical component of the velocity and α is the angle with the horizontal. So:

Vv=80*sin(10)=80*0.1736=13.888 m/s. 

So the vertical component of the velocity of the train is Vv=13.888 m/s.

Please help me to do this problem
Novosadov [1.4K]

Answer:

we got time and velocity over time.

so the distance is again the area underneath the graph

for a triangle with known base and height it's

4*10 / 2

distance traveled is 20

deceleration occurs when velocity decreases. that happens from t=2 till t=4

in 2 time-units we loose 10 units of velocity, so we decelerate by 5 units per 1 time

a (from t=2 to t=4) = -5v/t

You see a total eclipse of the sun. Three Saros cycles later, you find yourself at the same location.
alukav5142 [94]

Answer:

The correct answer is B. You would not have to travel far to see another total eclipse  .

Explanation:

it is said that the way to predict or know beforehand if there is a lunar or solar eclipse is just to know the what is called the saros which are periods of exactly 223 synodic months and the eclipses are repeated or occurred in the same location every 3 Saros cycles.

The population of ticks in the forest and the temperature of the air have an indirect relationship. As the air temperature incre
Ksju [112]

Answer:

Based on this relationship scenario, as it is known that Ticks aren't capable of drinking water so they require a climate with high humidity to stay hydrated. A climate with high air temperature and low humidity is not ideal. At these condition, a tick can not comfortably survive and this is vice versa.

What are the SI units for liquid volume?
Gemiola [76]
SI units for volume don't care whether you use them to describe
a solid, a liquid, a gas, or a volume of vacuum.

The units are the liter, and the cubic meter (1,000 liters).
