The period of the tan function is π so (∅ + π) would yield the same value as ∅
F(∅ + π) = 3

DedPeter [7]

Answer:

d = 142.5 m

Explanation:

This is a vector exercise. Let's calculate how much the boat travels in the 40s

d₀ = $v_{b}$ t

d₀ = 0.75 40

d₀ = 30 m

Let's write the kinematic equations

Boat

x = d₀ + $v_{b}$ t

x = 0 + $v_{h}$ t

At the meeting point the coordinate is the same for both

d₀ + $v_{b}$ t = $v_{h}$ t

t ( $v_{h}$ - $v_{b}$ ) = d₀

t = d₀ / ( $v_{b}$ - $v_{h}$ )

The two go in the same direction therefore the speeds have the same sign

t = 30 / (0.95-0.775)

t = 150 s

The distance traveled by man is

d = $v_{h}$ t

d = 0.95 150

d = 142.5 m

3 resistors are connected in parallel, each with resistance between 1 and 10 Ω. What is NOT a possible value for the overall equ

Leno4ka [110]

Answer:

Therefore,

1/3 ≤ Re ≤ 10/3 ohms

The equivalent resistance CANNOT be any value outside the boundary above

That is

Re CANNOT be greater than 10/3 ohms and CANNOT be less than 1/3 ohms, given that R1,R2,R3 are all between 1 and 10ohms.

Explanation:

For a parallel resistor arrangement.

The equivalent resistance (Re) of the three resistors is given by;

1/Re = 1/R1 + 1/R2 + 1/R3

1/Re = (R2R3 + R1R3 + R1R2)/R1R2R3

Re = R1R2R3/(R2R3 + R1R3 + R1R2)

Therefore, if R1,R2,R3 are between 1-10ohms

We need to calculate the range of values of Re.

Taking the lower bound 1

R1= R2=R3= 1ohms

Re = 1/(1+1+1)

Re = 1/3 ohms

Taking the upper bound 10 ohms

R1= R2=R3= 10 ohms

Re = 1000/(100+100+100)

Re = 1000/300

Re = 10/3 ohms

Therefore,

1/3 ≤ Re ≤ 10/3 ohms

The equivalent resistance CANNOT be any value outside the boundary above

That is

Re cannot be greater than 10/3 ohms and cannot be less than 1/3 ohms, given that R1,R2,R3 are all between 1 and 10ohms.

A metal wire of resistance 48 ???? is cut into four equal pieces that are then connected side by side to make a new wire that is

jeka57 [31]

Answer:

Explanation:

Resistance of wire, R = 48 ohm

It is cut into four pieces.

As we know that the resistance is directly proportional to the length of the wire.

So, the resistance of each piece of wire, R' = 48 / 4 = 12 ohm

Now the four pieces are connected in parallel. So the equivalent resistance is given by

$\frac{1}{R_{eq}}=\frac{1}{R'}+\frac{1}{R'}+\frac{1}{R'}+\frac{1}{R'}$

$\frac{1}{R_{eq}}=\frac{1}{12}+\frac{1}{12}+\frac{1}{12}+\frac{1}{12}$

Req = 3 ohm
