Answer:

if g on Earth= 9.8m/s²

then g on moon will be 0.38 *9.8=3.7m/s²

Mass of a basketball player is 50kg then the weight will be 50*3.7=186.2N

If a personal pan pizza (6 inches in diameter) has 600 calories, how many calories would you consume if you were to eat a large

Neko [114]

Answer:

2400 calories

Explanation:

given,

diameter of pizza,d₁ = 6 inches

calories of the 6 inches pizza = 600 calories

diameter of large size of pizza, d₂ = 12 inches

calories of the 12 inches pizza = ?

Area of the 6 inches pizza

A₁ = π x 3² = 9 π

Area of the 12 inches pizza

A₂ = π x 6² = 36 π

Ratio of 12 inch pizza to 6 inches

= $\dfrac{36\pi}{9\pi}$

= $\dfrac{4}{1}$

calories of the pizza

$\dfrac{x}{600}=\dfrac{4}{1}$

x = 2400 calories

Pizza of 12 inches is of calories is equal to 2400 calories

* A ball is projected horizontally from the top of

bagirrra123 [75]

Explanation:

Given

Ball is projected horizontally from a building of height $h=19.6\ m$

time taken to reach ground is given by

$\text{Cosidering vertical motion}\\\Rightarrow h=ut+0.5at^2\\\Rightarrow 19.6=0+0.5\times 9.8t^2\\\Rightarrow t^2=4\\\Rightarrow t=2\ s$

(b) Line joining the point of projection and the point where it hits the ground makes an angle of $45^{\circ}$

From the figure, it can be written

$\Rightarrow \tan 45^{\circ}=\dfrac{h}{x}\\\\\Rightarrow x=h\cdot 1\\\Rightarrow x=19.6$

Considering horizontal motion

$\Rightarrow x=u_xt\\\Rightarrow 19.6=u_x\times 4\\\Rightarrow u_x=4.9\ m/s$

$\Rightarrow v^2-u_y^2=2as\\\Rightarrow v^2-0=2\times 9.8\times 19.6\\\Rightarrow v=\sqrt{384.16}\\\Rightarrow v=19.6\ m/s$

Thus, the ball strikes with a vertical velocity of $19.6\ m/s$

PLEASE HELP! If the period of a mass spring oscillator is 8π s and the spring constant is 2 N/m, how much mass is attached?

xxTIMURxx [149]

The period of a mass-spring system is:

T = 2π $\sqrt{m/k}$

T = period, m = mass, k = spring constant

Given values:

T = 8π s

k = 2 N/m

Plug in and solve for m:

8π = 2π $\sqrt{m/2}$

$\sqrt{m/2}$ = 4

m/2 = 16

m = 32 kg

Choice A
