Answer:
a. Microwaves—3 and infrared waves—1
Explanation:
Microwaves and infrared waves are both part of the electromagnetic spectrum, but they have different frequency and wavelength.
In particular:
- Microwaves are long-wavelength electromagnetic waves, with wavelength between 1 mm and 1 m. Their wavelength is longer than visible light
- Infrared waves are also long-wavelength electromagnetic waves, but their wavelength is shorter than microwaves: between 700 nm and 1 mm. Their wavelength is also longer than visible light.
The two types of waves are also used for different purposes. In particular:
- Infrared waves are emitted by any hot object, and their intensity depends on the temperature of the object. Therefore, they are used in astronomy to show the heat released by astronomical objects (option 1)
- Microwaves are used to study the Cosmic Microwave Background (CMB). This is electromagnetic radiation that permeates the whole universe, and its wavelength depends inversely on the local temperature. Therefore, areas with longer wavelength have lower temperature, and viceversa. Therefore, microwaves are used to measure temperature differences in space (option 3).
Answer:
The Speaker of the House is responsible for administering the oath of office to the Members of the U.S. House of Representatives, giving Members permission to speak on the House floor, designating Members to serve as Speaker pro tempore, counting and declaring all votes, appointing Members to committees, sending bills Explanation:
a) Speed: It is the ratio of distance covered and time interval to cover that distance
it is given as 
b) Direction: it will define for vector quantities and shows the required direction for it
c) Velocity : It is rate of change in position or it is ratio of displacement and time
d) Vector : it is a type of physical quantity which will be defined by magnitude and direction both
e) Position : it is defined as the distance with respect to a given reference or origin
f) Acceleration : it is defined by rate of change in velocity.
g) Force = it is push or pull on an object which will create acceleration to the object
F = ma
it is product of mass and acceleration
h) Newton : it is SI unit of force or we measure force in this unit
