Answer:
physics
Explanation:
physics needs to be steady whether you like it or not it helps you in life so everybody must study physics no matter is in Uganda USA and plenty more countries there must be physics to dare to be studied
Answer:electrostatic interactions, hydrogen bonding, van der waals interactions.
Explanation:the above listed are the interaction that that contribute
Answer:
7km
Explanation:
The angle of depression is congruent to the angle of elevation and can be explained as angle below horizontal in which the person observing an object must view for him/her to view object's that are lower than him/her.
In angle of depression, there is assumption that object is closer to the person observing it, so there is parallel horizontal for both observing and object been observed.
hot air balloon 2 km high,
there exist two triangles
From trigonometry
Tanx= opposite/adjacent
Opp= 2km
Adj= X1
first triangle have base length of
Tan(16)=2/X1
X1=2/ tan(16)
X1=6.97
For Second triangle
Tanx= opposite/adjacent
Opp= 2km
Adj= X2
the other with a base length of
X2=2/tan(84)
X2=0.21
Therefore,, the total distance between the two towns is
x1+x2=6.97+0.21=7.18km
The correct answer to the problemis velocity. I did the test.
The ordinary light bulb that we use in everyday life is either LED (containds small light emiting diods) or it contains a wire that is heated to a high temperature and as a result light is produced.
For his demonstrations Tesla used bulbs that did not contain any part inside. Instead of any part there was a gas inside. These type of bulbs are still used. Their main advantage is that they do not require much energy to produce light.
Inside his light-bulbs Tesla and others put a noble gas such as neon, xenon and argon. Also, sometimes there was a phosphorus on the outside part of a light-bulb. When this light-bulb is brought into electromagnetic field it produces light. This happens due to foto-electric induction. When gas is positioned inside EM field gas gets exited. This causes for electrons to jump out of their positions and emit light. This can be achieved wirelesly as long as EM field is strong enough.
