Maybe push or pull an object with a large amount of mass? you are force a (pushing through object) aka making contact. i hope i helped not good with physics :)
Answer:I would guess a plane
Assuming they all Thad the same velocity....
Answer:
23. 4375 m
Explanation:
There are two parts of the rocket's motion
1 ) accelerating (assume it goes upto h1 height )
using motion equations upwards
Lets find the velocity after 2.5 seconds (V1)
V = U +at
V1 = 0 +5*2.5 = 12.5 m/s
2) motion under gravity (assume it goes upto h2 height )
now there no acceleration from the rocket. it is now subjected to the gravity
using motion equations upwards (assuming g= 10m/s² downwards)
V²= U² +2as
0 = 12.5²+2*(-10)*h2
h2 = 7.8125 m
maximum height = h1 + h2
= 15.625 + 7.8125
= 23. 4375 m
Answer: The rating scale that is used in food history inventory is from 1 to 8.
Explanation:
In this case the participants have to rate 24 items on a scale of 1 to 8.There are variety of questions related to food or fooding habits.
The questions like do you go out for food?
Do you like bread ? if yes how will you rate it on a scale of 1 to 8.
The questions like this has to be answered in a way . It is done in order to see the preferences and false memory regarding the food preference that people have.
I believe your answer would be D- Physical properties of matter effect the chemical properties of matter.
Hope this helps. Tell me if I'm right.
