Answer:

(A) Their high energy

Explanation:

The higher the energy of the x-ray the more "likely" they will pass through.

The x-ray is electromagnetic energy caused by energy changes in an electron.

X-ray are energetic and have enough energy to break up molecules. That is what reveals the bad or damaged cells in our body.

Which vector should be negative?

pentagon [3]

Answer:

The velocity of a falling object

Explanation:

The positive X axis is towards right and positive Y axis is towards up, so North direction is positive

A vector with less than 1 magnitude is not negative, because its magnitude may be in between 0 and 1 which is positive vector.

Any vector whose magnitude is greater than 1 is never be a negative vector.

The velocity of a falling object is towards bottom, that is towards negative Y axis. So that vector is negative.

Toy car in a science experiment covers 1.6 meters in half a second. If a the car travels at a steady speed, how far will it go i

Tanzania [10]

The answer is D. 32 m.

The simple equation that connects speed (v), time (t), and distance (d) can be expressed as:
$v= \frac{d}{t}$ ⇒ $d=v*t$

It is given:
$v = \frac{1.6m}{0.5s} = \frac{1.6m*2}{0.5s*2}= \frac{3.2m}{1s} = 3.2 m/s$
t = 10 s
d = ?

So:
$d= v*t=3.2m/s*10s = 32m$

Anna35 [415]

Answer:

d = 76.5 m

Explanation:

To find the distance at which the boats will be detected as two objects, we need to use the following equation:

$\theta = \frac{1.22 \lambda}{D} = \frac{d}{L}$
