Answer:

the force of gravity (Fgrav) and the normal force (Fnorm).

Explanation:

Neglecting friction and air resistance, a roller coaster car will experience two forces:the force of gravity (Fgrav) and the normal force (Fnorm). The normal force is directed in a direction perpendicular to the track and the gravitational force is always directed downwards.

Answer:

Gravity force (g-force) and normal force

Explanation:

Neglecting friction and air resistance, a roller coaster will experience two forces which are the force of gravity (Fgrav) and the normal force (Fnorm).

For RTK to work, what do we need besides two or more receivers collecting data from a sufficient number of satellites simultaneo

Liula [17]

Answer:

phase measurement and the information content

Explanation:

The full form of RTK is Real Time Kinematic. It is used for satellite navigation technique to increase the precision of the position data that is derived from the positioning systems based on satellites like the NavIC, GPS, Galileo, BeiDou and GLONASS. It takes help of the measurements of phase of signal's carrier wave and also the information content of these signals and it also relies on the single interpolated virtual station in order to provide the real time corrections and provide correct and accurate information.

What is the De Broglie wavelength of an electron under 150 V acceleration?

yanalaym [24]

Answer:

0.1 nm

Explanation

Potential deference of the electron is given as V =150 V

Mass of electron $m=9.1\times 10^{-31}$

Let the velocity of electron = v

Charge on the electron $=1.6\times 10^{-19}C$

plank's constant h = $6.67\times 10^{-34}$

According to energy conservation $eV =\frac{1}{2}mv^2$

$v=\sqrt{\frac{2eV}{M}}=\sqrt{\frac{2\times 1.6\times 10^{-19}\times 150}{9.1\times 10^{-31}}}=7.2627\times 10^{-6}m/sec$

Now we know that De Broglie wavelength $\lambda =\frac{h}{mv}=\frac{6.67\times 10^{-34}}{9.1\times 10^{-31}\times 7.2627\times10^6 }=0.100\times 10^{-9}m=0.1nm$

What is meant by the dead state. Discuss its significance.

Jlenok [28]

Answer and Explanation:

Dead state can be defined as the state in which both the are ambient properties and the system properties are coincident to each other.

Since the surroundings are similar and these surroundings are fixed also, there will be no kinetic energy and also the gravitational potential energy for both the systems is also equal.

Practically, in thermodynamic studies, the Gravitational potential energy of the system is negligible. This state holds significance because it leads to the termination of all the processes that are spontaneous in nature.
