Answer: Anthony will be warmer after the game.

Explanation :

Anthony and Maelynn are watching a football game outside on a sunny day. Anthony is wearing a black shirt and Maelynn is wearing a white shirt. Anthony will be warmer after the game. The black color is a good absorber of radiation and a bad reflector.

The black color absorbs heat until a thermal equilibrium is attained. So, it is advisable to wear cotton clothes in summers not dark colored clothes.

Answer:

Anthony will be warmer after the game because he is wearing a black shirt. Dark colors absorb more thermal energy than light colors.

What is the energy of a photon of light having a wavelength of 4.5 x 10-7 meters? (Planck’s constant is 6.626 x 10-34 joule seco
Ivenika [448]
The answer is <span>4.4143 x 10-19 joules
</span>
The energy (E) is: E = h * f
h - Planck's constant
f - the frequency

The frequency (f) is: f = c/∧
c - the speed of light
∧ - the wavelength

Hence:
E = h * f = h * c / ∧

We know:
h = 6.626 x 10⁻³⁴<span> Js
c = </span>2.998 x 10⁸<span> m/s
</span>∧ = 4.5 x 10⁻⁷<span> m

E = </span>6.626 x 10⁻³⁴ Js * 2.998 x 10⁸ m/s / 4.5 x 10⁻⁷ m 
E = 4.4143 x 10⁻³⁴ ⁺ ⁸ ⁻ ⁽⁻⁷⁾ J 
E = 4.4143 x 10⁻¹⁹ J

While brayden is traveling along a straight interstate highway, he notices that the mile marker reads 260. Brayden travels until
Yuki888 [10]

Answer:

<em>displacement = -85 miles</em>

Explanation:

<u>Displacement </u>

It's a magnitude used to measure the linear space between two points. It's computed as the subtraction of the final position minus the initial position which results in a vector. Notice the displacement only depends on the initial and final positions and not on the path the object has traveled.

Brayden starts to measure his position when the mile marker reads 260. Then he travels to the 150-mile marker and goes back to the 175-mile marker, his final position. As mentioned, the displacement only depends on the relative positions, so

displacement = 175 - 260 = -85 miles

A bat strikes a 0.145-kg baseball. Just before impact, the ball is traveling horizontally to the right at 60.0 m/s , and it leav
nata0808 [166]

Answer:

F = -307.4 N

Explanation:

It is given that,

Mass of the baseball, m = 0.145 kg

Initial speed of the baseball, u = 60 m/s

Final speed of the baseball, v=65\ cos(30)=56.29\ m/s

Time of contact, t=1.75\ ms=1.75\times 10^{-3}\ s

(a) It is assumed to find the horizontal component of average force. It is given by :

F=m\dfrac{v-u}{t}

F=0.145\dfrac{56.29-60}{1.75\times 10^{-3}}

F = -307.4 N

So, the horizontal component of average force is 307.4 N. Hence, this is the required solution.
