A falling person at low altitude will reach terminal velocity after about 12 seconds, falling some 450 m (1,500<span> ft) in that time. He or she will then maintain this speed without falling any faster.</span>

Which member of each pair is more soluble in diethyl ether? Why?<br> (c) MgBr₂(s) or CH₃CH₂MgBr(s)
White raven [17]

CH3CH2MgBr is more soluble in diethyl ether .

We know that polar solvent dissolve in polar solvent very perfectly . as diethyl ether is a polar solvent so it have dipole -dipole interaction .

Hence the compound with similar interaction can dissolve in diethyl  ether .

Here , MgBr2  is an ionic compound . there is ion-ion interactions occurs which is not similar to dipole -dipole interaction in diethyl ether .hence the solubility of MgBr2 in diethyl ether is less .

but in case of CH3CH2MgBr there are both polar and nonpolar end .CH3CH2 is the nonpolar end and MgBr is the polar end .

thus with the nonpolar end solute interact using depression forces and with polar end solute interact using dipole-dipole interaction . so CH3CH2MgBr is more soluble .

Express the chemical reaction between hydrogen and oxygen elements for the formation of water in word equation and chemical equa
White raven [17]

Answer:

Two moles of hydrogen gas combine with one mole of oxygen gas to produce two moles of water.

2H_{2} O + O_{2}  -> 2H_{2}O

Explanation:

This is the required amount of each element to synthesize water. The equation has been balanced using coefficients.

Make a diagram showing how communication satellites could be used to relay
alexdok [17]

Answer:

Explanation:

Satellite acts as a relay station for earth sources. A transmission station sends the information to the satellite, which in turn retransmits to the receiving stations. The original signal being transmitted from the earth station to the satellite is called uplink of 6 GHz The retransmitted signal from the satellite to the receiving station is called downlink of 4 GH frequency. The transponder is the transmitter-receiver combination in a transponder.
