In a series circuit, the current drops across each resistance.
a. True
b. False

Answers

Answer 1

Answer: That's false. In a series circuit, the current is the same
at every point all around the circuit.

It's the voltage that drops across each resistance.

What do ultrasounds use?radio waves
ultraviolet waves
light waves
sound waves

Answers

Ultrasounds are used in the medical profession for the purpose of diagnosis. Ultrasounds uses high frequency sound waves. Thus, the correct option is D.

What are Ultrasounds?

Ultrasound are the sound waves with frequencies which are higher than the upper audible limit of normal human hearing. Ultrasound is not different from normal audible sound frequencies in its physical properties, except that humans cannot hear these sound.

Ultrasound is used in diagnostics where it is also called as sonography or diagnostic medical sonography. It is an imaging method which uses sound waves to produce images of structures within the body of a person. The images produced can provide valuable information for the purpose of diagnosing and directing treatment for a variety of diseases and conditions.

Therefore, the correct option is D.

Timmy bikes to school 3 kilometers east and 2 kilometers south. What is Timmy's final displacement?

Answers

Answer:

3.6km South East

Explanation:

Displacement is the shortest distance between the starting point and the ending point and the direction it is displaced in. To calculate the displacement we can use the pythagoras theorem because the 3km East and the 2km south form the two shorter sides of a right angled triangle between the starting and ending points. So, the displacement is the length C of the triangle which we can calculate as follows:

Pythagoras Theorem:

a^2+b^2=c^2

(2)^2+(3)^2=c^(2)

4+9=c^2

Square root 13 = c

c=3.6km (1dp)

The total displacement is 3.6km and is in the approximate direction of South East (because he travelled east and south).

Why do deer depend on plants to survive

Answers

Deer depend on plants to survive because they are herbivores. Herbivores are animals that only eats plants and fruits in order to survive. Deer's meal includes grass and evergreen plants. If grass is unavailable, they eat whatever food like fallen leaves, twigs, bushes and other woody plants.

Name 2 forces acting on an object at rest Only need 1 got gravity

Answers

You mean like a box sitting on a table.

One force is the force of gravity, pulling downward on the box.

Now, you know that the forces acting on the box must be balanced, because
if they're not, then the box would be accelerating. But it's just sitting there, so
there must be some other force, just exactly the right strength and direction to
exactly cancel the force of gravity on the box, so that the net force on it is zero.

The other force is the force of the table pushing upward on the box. It's called
the "normal force".

An emergency relief plane is dropping a care package from a plane to a group of medical personnel working for a relief agency in an African village. The package is designed to land in a small lake, inflate an attached raft upon impact, and finally resurface with the raft side down. The plane will be moving horizontally with a ground speed of 59.1 m/s. The package will be dropped a horizontal distance of 521 m from the intended target location. At what altitude above the pond must the plane be flying in order to successfully accomplish this feat?

Answers

Answer:

The altitude of the plane is 379.5 m.

Explanation:

Initial horizontal velocity, u = 59.1 m/s

Horizontal distance, d = 521 m

let the time taken by the packet to cover the distance is t.

Horizontal distance = horizontal velocity x time

521 = 59.1 x t

t = 8.8 s

let the vertical height is h .

Use second equation of motion in vertical direction.

$h = u t + 0.5 gt^2\n\nh = 0 + 4.9 * 8.8*8.8\n\nh= 379.5 m$

Final answer:

The plane must be flying at an altitude of approximately 194.89 m above the pond.

Explanation:

To successfully drop the care package in the small lake, the plane must be flying at a certain altitude above the pond. We can use the horizontal distance and the ground speed of the plane to calculate the time it takes for the package to reach the target location. Then, using the time and the equation for free fall, we can find the altitude above the pond.

First, we calculate the time it takes for the package to reach the target location:

Horizontal distance = 521 m
Ground speed = 59.1 m/s
Time = Horizontal distance / Ground speed = 521 m / 59.1 m/s = 8.81 s

Next, we use the equation for free fall to find the altitude above the pond:

Acceleration due to gravity, g = 9.8 m/s^2 (assuming no air resistance)
Time for free fall, t = 8.81 s
Altitude above the pond = 0.5 * g * t^2 = 0.5 * 9.8 m/s^2 * (8.81 s)^2 = 194.89 m

Therefore, the plane must be flying at an altitude of approximately 194.89 m above the pond in order to successfully accomplish this feat.
