The correct answer is A. Gamma Rays. They have the shortest wave-length, and the highest frequency.

Hope I helped. :)

Answer: Gamma rays

Explanation: The given waves belong to the electromagnetic spectrum which consists of different electromagnetic radiations arranged in terms of increasing wavelengths or decreasing frequencies.

$E= h\times \nu$

$\nu=\frac{c}{\lambda}$

Thus $E=\frac{h\times c}{\lambda}$

E= energy

$\nu$ = frequency

c = speed of light

$\lambda$ = wavelength

Thus frequency and wavelength are inversely related. The waves having high energies ave high frequencies and have shorter wavelengths.

Thus gamma rays having highest energy have highest frequency and shortest wavelength.

Using the midpoint and the distance formulas, calculate he coordinate of the midpoint and the length of the segment.

arsen [322]

Answer:

Explanation:

Formula to calculate the distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ is,

d = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Therefore, length of CD having coordinates C(3,1) and D(3, 3),

CD = $\sqrt{(3-3)^2+(1-3)^2}$

= 2 units

Formula to find the midpoint of CD is,

M = $(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

= $(\frac{3+3}{2},\frac{1+3}{2})$

= (3, 2)

Therefore, length of CD = 2 units and (3, 2) are the coordinates of the midpoint of CD.

A boat displaces a volume V of water as it floats on a fresh-water lake. When the boat moves into the ocean, what volume of salt

Mamont248 [21]

Answer:

Option (b)

Explanation:

let the weight of boat is W. In equilibrium condition, the weight of boat is equal to the buoyant force acting on the boat.

The buoyant force acting on the boat is equal to the weight of water displaced by the boat.

In case of fresh water:

Weight of the boat = weight of fresh water displaced by the boat

W = Volume of fresh water displaced x density of fresh water x g

W = V x 1 x g

W = V x g ....... (1)

In case of salt water:

Let the volume of salt water displaced is V'.

Weight of the boat = weight of salt water displaced by the boat

W = Volume of salt water displaced x density of salt water x g

W = V' x 1.02 x g ..... (2)

Equate equation (1) and equation (2), we get

V x g = V' x 1.02 x g

V' = 0.98 V

Thus, option (b) is true.

An object is moving at a velocity of 3m/s. It accelerates to a velocity of 5.5m/s over a time of 9 s. What acceleration did it e

alexira [117]

Answer:

Acceleration(a) = $\displaystyle\frac{v - u}{t}$

v = final velocity = 5.5 m/s

u = initial velocity = 3 m/s

t = time = 9s

$\displaystyle a = \frac{3-5.5}{9}$

$a = \displaystyle\frac{-2.5}{9}$

$a = -0.278 \ m/s^2$ (approx)
