A _______ satellite records reflected wavelengths from Earth's surface.

1 answer:

8 0

A visible satellite images records reflected wavelengths from Earth's surface.

Visible satellite images record visible light coming from the sun that is reflected by clouds, land, oceans or snow and ice.
There is a big difference between visible and infrared images since visible images record reflected light rather then emitted radiation.

In a downhill ski race, surprisingly, little advantage is gained by getting a running start. (This is because the initial kineti

Sergio [31]

Answer:

Part a)

$v_f = 25.2 m/s$

$t = 5.48 s$

Part b)

$v_f = 25.32 m/s$

$t = 4.96 s$

Explanation:

Part a)

When ski start from rest

$v_f^2 - v_i^2 = 2 a d$

on this inclined plane we know that the acceleration is given as

$a = g sin\theta$

$a = 9.81 sin28$

$a = 4.6 m/s^2$

now for final speed

$v_f^2 - v_i^2 = 2 a d$

$v_f^2 - 0 = 2(4.6)(69)$

$v_f = 25.2 m/s$

now time taken by the ski to reach the bottom is given as

$v_f = v_i + at$

$25.2 = 0 + 4.6 t$

$t = 5.48 s$

Part b)

Now when ski start with initial speed of 2.5 m/s

then we will have

$v_f^2 - v_i^2 = 2 a d$

$v_f^2 - 2.5^2 = 2(4.6)(69)$

$v_f = 25.32 m/s$

now time taken by the ski to reach the bottom is given as

$v_f = v_i + at$

$25.32 = 2.5 + 4.6 t$

$t = 4.96 s$

A plane is flying in a horizontal line describe the motion of the plane in this situation

Andrei [34K]

Answer:

The horizontal speed of a projectile is constant for the duration of its flight. This is because, once launched, there are no horizontal forces acting on the projectile (air resistance is usually ignored because it is very small) so horizontally the projectile will travel at a constant speed. For any calculations involving the projectile's horizontal motion, we use

distance=speed×time

d=vt

Express each of the following in ms -1 a) 18kmh-1

vovangra [49]

1km=1000m; 1hr=3600secs
1km/hr=1000/3600= 5/18m/sec
To convert km/hr into m/sec, multiply the number by 5 and then divide it by 18.

18kmh-1= 18•5=90
90/18=5
5ms-1
