"Waves can exist in solids, liquids, and gases."
is the ONLY accurate statement.
The word "only" in the other 3 statements makes them
not accurate at all.
Answer:
The right solution is "0.50 m/s²". A further explanation is provided below.
Explanation:
The given values are:
Mass,
m = 50 kg
Speed,
v = 10 m/s
Rolling friction acting backward (south),
f = 10 N
Air resistance acting backward (south),
= 15 N
The total force acting will be:
⇒ 
On substituting the given values, we get
⇒ 
⇒ 
Now,
⇒ 
On substituting the given values, we get
⇒ 
⇒ 
The horizontal acceleration will be "0.50 m/s²" because the (-)ve sign indicates it in south direction.
Ionic bond is formed due to the transfer of electrons from one atom to the other. In this bond, one atoms (the donor) loses (donates) one or more electron(s) to the other atom (the acceptor) in order for both to become stable.
Examining the choices we have, we will find that K needs to lose one electron while Br needs to gain one electron in order for both to be stable. Therefore, K loses one electron that is gained by Br.
Based on this, the bond in KBr is considered ionic.
The right choice is:
<span>K and Br </span>
