Answer:

<u>D. There will be a low current drop across it.</u>

Explanation:

The current may be substantially reduced by inserting a high resistance between two points (for the sake of this example, we'll use A and B). High resistances in an electrical current tend to reduce greatly the flow of charge, and they also have large potential drops across them.

If the resistor is in series with the rest of the circuit then a is the correct answer. The voltage across the resistor in series with another resistor is
$V \frac{R}{R+r}$
where R is the big resistor and r is the small one and V is the total voltage drop across both. This is called a voltage divider

400m in 32sec: (400/32)>12.5meters per second>
(12.5)(60)(60)(1/1000)=45km per hour
Constant speed would mean that the two forces are equivalent

In attempting to pass the puck to a teammate, a hockey player gives it an initial speed of 2.8 m/s. However, this speed is inade

erastova [34]

Answer:

3.95979 m/s

Explanation:

t = Time taken

u = Initial velocity

v = Final velocity

s = Displacement

a = Acceleration

$v^2-u^2=2as\\\Rightarrow as=\frac{v^2-u^2}{2}\\\Rightarrow as=\frac{0^2-2.8^2}{2}\\\Rightarrow as=-3.92$

Here $s=\frac{1}{2}s$

$\\\Rightarrow as=-7.84\ m/s^2$

$v^2-u^2=2as\\\Rightarrow -u^2=2as-v^2\\\Rightarrow u=\sqrt{v^2-2as}\\\Rightarrow u=\sqrt{0^2-2\times -7.84}\\\Rightarrow u=3.95979\ m/s$

Initial velocity of the puck should be 3.95979 m/s

Harry is a professional astronomer. The pictures below show two types of telescopes Harry owns.

The best answer is
C) reflecting telescope, because it can be made large enough to gather more radiations (or light) from distant objects.

Reflecting telescopes, unlike refracting telescopes, can be made larger and larger to collect more light, with more precision, from larger distances. Refracting telescopes generally are not used for any demanding purposes, such viewing objects in space by professional astronomers.
