A motorboat travels 92 km in 2 hours going upstream. It travels 132 km going downstream in the same amount of time. What is the

taurus [48]

Answer:

The speed on boat in still water is $56 \frac{km}{h}$ and the rate of the current is $10 \frac{km}{h}$

Explanation:

Since speed , $v= \frac{Distance\, traveled(D)}{Time\, taken(t)}$

Therefore speed of motor boat while traveling upstream is

$v_{upstream}=\frac{92}{2}\frac{km}{h}=46\frac{km}{h}$

and speed of motor boat while traveling downstream is

$v_{downstream}=\frac{132}{2}\frac{km}{h}=66\frac{km}{h}$

Let speed of boat in still water be $v_b$ and rate of current be $v_w$

Therefore $v_{upstream}=v_b-v_w=46\frac{km}{h}$ ----(A)

and $v_{downstream}=v_b+v_w=66\frac{km}{h}$ ------(B)

Adding equation (A) and (B) we get

$2v_b= (46+66) \frac{km}{h}=112 \frac{km}{h}$

=> $v_b= 56 \frac{km}{h}$ ------(C)

Substituting the value of $v_b$ in equation (A) we get

$v_w= 10 \frac{km}{h}$

Thus the speed on boat in still water is $56 \frac{km}{h}$ and the rate of the current is $10 \frac{km}{h}$

A single particle of a compound is a

Sav [38]

Answer:

mixture

Explanation:

All matter is made of particles; these can be single atoms or atoms chemically joined to make molecules. Using this fact, matter can be classified into three broad groups: elements, compounds and mixtures. In an element, all the atoms are of the same type. If more than one type of atom is chemically joined, then a compound has been formed. If more than one type of atom or molecule is contained in the same substance, and the particles aren't chemically joined, this is a mixture.

SVETLANKA909090 [29]

Answer:

Negative

Positive

Explanation:

When a positive charge balloon is brought near the neutral metal can, the positive charge in the ballon, delocalization and arrangement of like charges occurs. The positive charge then flow to the an end while the negative charges flows to the other end.

Thus, after being touched, the charge on the can is negative.

And, If not touched, the charge on the ballon remains positive.
