C, planets orbit around the sun because of gravity
Answer:
The frog's horizontal velocity is 0.2 m/s.
Explanation:
To solve this problem, we must first remember what velocity is and how we solve for it. Velocity can be solved for using the formula x/t, where x represents horizontal distance and t represents time (in seconds), that it takes to travel this distance. If we plug in the given numbers for these variables and solve, we get the following:
v = x/t
v = 0.8m/4s
v = 0.2 m/s
Therefore, the correct answer is 0.2 m/s. We can verify that these units are correct because the formula calls for distance divided by time, so meters per second is a sensible answer.
Hope this helps!
Answer:
2,38kg
Explanation:
Mass in function of time can be found by the formula: 
, where 
is the initial mass, t is the time and k is a constant.
Given that a sample decay 1% per day, that means that after first day you have 99% of mass.
, but 
, so we have 
, then 
Now using k found we must to find 
.
The volume of the jet fuel is 1.213 x 10⁵ cm³.
<h3>What is density?</h3>
Density is a physical property that measures the ratio of mass to volume occupied by an object.
Density = mass/volume
Volume = mass/density
<h3> Volume of the jet fuel</h3>
The volume of the jet fuel is calculated as follows;
Volume = (97500 g)/(0.804 g/cm³)
Volume = 1.213 x 10⁵ cm³
Thus, the volume of the jet fuel is 1.213 x 10⁵ cm³.
