Answer:
10.03 s is the time the decoy is in the air
Explanation:
From the information given we know:
- because is measured clockwise from horizontal.
- The initial speed of the decoy is the plane's speed at the moment of release
We will need to work in meters and m/s, so
The horizontal motion of a projectile is given by:
because , this becomes
We have that , solving for <em>t, </em>we have
The answer is A.
Hope I helped.
Answer : <em>Her weight is lower on Venus because the acceleration due to gravity is lower.</em>
Explanation :
Venus is also called as Earth's twin. This is because both the mass and the size of Earth and Venus are almost same. The acceleration due to gravity on earth is while on Venus is .
So, when Shari measure her weight on Venus she found her weight is lower on Venus. This is because the acceleration due to gravity is lower on the surface of Venus as compared to the Earth.
Since,
i.e. weight depends on g.
<em>So, correct prediction is (b)</em>
Ok so if each side is 4.53 cm, we can multiply 4.53 x 4.53 x 4.53 to get the volume (since v= l x w x h). Density equals mass/volume, so
519 g/4.53 cm
114.57 g/cm^3 (since none of the units cancel)
