Streams of glowing gas that shoot out from the sun is called Prominence. It is a loop of incandescent, cool gas that extends way above the sun's edge can be viewed from Earth. These streams usually follow the magnetic field lines that are curved from an area of on magnetic polarity to an area of the opposite magnetic polarity. These streams can last for hour or even weeks.

Answer:

PARABOLIC, EARTH, VERTICAL, INERTIAL ang PHYSICAL LAWS

Explanation:

In this exercise you are asked to complete the missing words.

When the steel ball falls on the constant speed car, it follows a PARABOLIC path in the reference frame fixed to EARTH, but a VERTICAL straight line in the reference frame of the constant speed car. Without a fixed frame of reference, you cannot tell whether or not you are in an INERTIAL frame of reference. All frames of reference that move at constant speed relative to each other are PHYSICAL LAWS__equivilent__.

A 56 kg boat that is 7.6 m in length is initially 7.6 m from the pier. A 39 kg child stands at the end of the boat closest to th

svlad2 [7]

Answer:

Explanation:

Given

mass of boat $M=56\ kg$

mass of Person $m=39\ kg$

Length of boat $L=7.6\ m$

Center of mass of boat and child

$x_{cm}=\frac{M\times 0.5L+m\times L}{M+m}$

$x_{cm}=\frac{56\times 0.5\times 7.6+39\times 7.6}{56+39}$

$x_{cm}=\frac{509.2}{95}$

$x_{cm}=5.36---1$

when child reaches another end of boat, boat is shifted by x cm

Center of mass of the system will remain the same

$x'_{cm}=\frac{M\times (x+0.5L)+m\times x}{M+m}$

$x'_{cm}=\frac{56\times (x+0.5\times 7.6)+39\times x}{56+39}----2$

Equating 1 and 2 we get

$509.2=95x+212.8$

$x=3.12\ m$

Express 68 rations in dekarations

rewona [7]

You have to take note of the prefix because it gives you a hint of its value with respect to the base value. The base value is ratio. When the prefix is deka, that means that 1 ration is equal to 0.1 dekaration according to the metric system. The conversion is as follows:

68 rations * 0.1 dekarations/1 ration = 6.8 dekarations

What is static electricity and how does it differ from current electricity

sp2606 [1]

Answer:

1. Static electricity is caused by the build up of electrical charges on the surface of objects, while current electricity is a phenomenon from the flow of electrons along a conductor. 2. When objects are rubbed, a loss and/or gain of electrons occurs, which results in the phenomenon of static electricity.
