Answer:
A = 70cm³
B= 805 grams
Explanation:
(a) V = L×B×H
= 7cm × 5cm × 2cm
= 35cm × 2cm
= 70cm³
(b) Mass= volume × Density
= 70cm³ × 11.5g/cm³
=805 grams

Answer:
Average speed will be 30.30 m/sec
Explanation:
We have distance d = 10 km
Time to reach university to home = 20 min
We know that 1 hour = 20 min
So 20 minute
We have to find average speed
We know that distance = speed × time
So
So the average speed will be 30.30 m/sec
Answer:
Its goal is to explore the Kupier Belt, a region in space where comets originate
Explanation:
The Mid-Infrared Instrument (MIRI) is a telescope with abilities to see the mid-infrared region of the electromagnetic spectrum.The wavelength of this instrument is 5-28 microns. The Kupier belt is a region in space beyond Neptune.MIRI was developed to enable scientists study and explore the kupier belt to observe the far most galaxies, new stars that are formed and the comets invisible from the previous telescopes.
