Answer:
See below ~
Explanation:
An object will sink in water when its density is greater than that of water, which is 1 g/cm³.
Volume of the box is <u>1331 cm³</u>. (11³)
Maximum mass of sand will be 1331 g. [because 1331/1331 = 1 g/cm³]
- Volume of sand = Mass of sand / Density of sand
- Volume (sand) = 1331/3.5
- Volume (sand) = 380.29 cm³
If the volume of sand is <u>greater than 380.29 cm³</u>, the box will sink in water.
Answer:
A. during the day or night and in any weather conditions.
Explanation:
Ground-based radio telescopes can be used to collect data from distant objects in space during the day or night in any weather condition.
They do not depend or are they affected by weather and they pass well through them.
- Telescopes are devices used to obtain information about distant bodies usually astronomical in nature.
- Optical telescopes use the visible range of light and they are overwhelmed by the sun during the day.
- Bad weather conditions can also diminish the reception of light.
- They work best at night.
- Radio telescopes uses electromagnetic radiations and can work at any time and during any weather.
Answer:
c). 
Explanation:
As we know that weight of the automobile is given here
so weight = mass times gravity
now from Newton's law
