Answer:
A crab lives in the intertidal zone.
A crab spends most of its time scavenging for food in the sand.
Explanation:
These tell us where a crab lives and where/how it feeds.
"A crab has an exoskeleton." is a true statement about the characteristics of a crab, but tells us nothing of its interaction with the environment so is not niche.
"A crab will avoid predators by quickly moving underneath an object to hide."
is a true statement, but is too general to identify a niche. Could be modified to cover niche if it said something like "A crab will avoid predators by quickly moving underneath an abandoned seashell or a coral rock to hide."
A push or a pull on an object
Answer:
105 mg
Explanation:
Given that:
1 baked potato provides 30 mg of vitamin C.
So,
70 baked potatoes provide mg of vitamin C
Also,
70 potatoes = 20 lb
So,
20 lb potatoes provide mg of vitamin C
Thus,
1 lb potatoes provide mg of vitamin C
<u>Thus, 105 mg of Vitamin C are provided per pound of the potatoes.</u>

Answer:
The distance is
Explanation:
From the question we are told that
The size of Jupiter is
The length of the International Space Station is
The size of the International Space Station is
The angular size where the same one night and this angular size is mathematically represented as
Since is constant
substituting values
=>
Now we are told to convert to AU and 1 AU
So
Answer:
<em>A. 22 </em>
<em>B. NO</em>
Explanation:
<u>A.</u>
During a collision , <em>the net external force on the system is zero .</em>
hence , the total momentum of the system can be CONSERVED .
let the mass of frosty and snowflake be m ;
- initial velocity of frosty be = 25
- final velocity of frosty be = 13
- initial velocity of snowflake be = 10
- final velocity of snowflake be = x
therefore from principle of conservation of momentum ,
<em></em>
so ,
<u>answer for A. 22 </u>
<u>B</u>.
<em>The collision is NOT ELASTIC.</em>
this is because if it had been elastic , the coefficient of restitution should have been 1 but it isnot i.e
≠ 1
<em>thus it's an inelastic collision.</em>
