A student needs a 4-ohm resistor to complete a circuit. Only a large quantity of 1-ohm resistors are available. In order to comp
Tema [17]

Answer:

C) He should connect four 1-Ohm resistors in series

Explanation:

If there are n resistors connected in series, say R_1, R_2,...R_n, the total resistance of the connection is the sum of the individual resistances, ie for a series combination of n resistors, the following holds;

R_T=R_1+R_2+...+R_n.................(1)

where R_T is the total resistance.

Since the student needs a 4-Ohm resistor and the only available ones are 1-Ohm each, he should combine each of them in series.

R_T=1+1+1+1\\R_T=4-Ohms

Arocket launches at an angle of 33.6 degrees from the horizontal at a
babymother [125]

Answer:

Y component = 32.37

Explanation:

Given:

Angle of projection of the rocket is, \theta=33.6

Initial velocity of the rocket is, u=58.5

A vector at an angle \theta with the horizontal can be resolved into mutually perpendicular components; one along the horizontal direction and the other along the vertical direction.

If a vector 'A' makes angle \theta with the horizontal, then the horizontal and vertical components are given as:

A_x=A\cos \theta(\textrm{Horizontal or X component})\\A_y=A\sin \theta(\textrm{Vertical or Y component})

Here, as the velocity is a vector quantity and makes an angle of 33.6 with the horizontal, its Y component is given as:

u_y=u\sin \theta

Plug in the given values and solve for u_y. This gives,

u_y=(58.5)(\sin 33.6)\\u_y=58.5\times 0.55339\\u_y=32.373\approx32.37(\textrm{Rounded to two decimal places})

Therefore, the Y component of initial velocity is 32.37.
