Answer:
Its final velocity and how much time it takes to reach the water
Explanation:
The motion of the stone is a uniformly accelerated motion, so we can use the following suvat equation to determine its final velocity:
where
v is the final velocity
u = 0 is the initial velocity
is the acceleration of gravity
s = 52 m is the distance covered during the fall
Solving for v,
We can also find how much time it takes to reach the water, using the equation
where
v = 31.9 m/s is the final velocity
u = 0 is the initial velocity
t is the time
And solving for t,
I believe they are called nonohmic materials. According to ohms law the current trough a current carrying conductor is directly proportional to the potential difference (voltage) at a constant resistance. Non-ohmic conductors or materials are those materials that do not obey the ohms law, their resistance increases as the current increases. Ohmic materials are those that obeys the ohms law such that the voltage and current are proportional- doubling the potential difference doubles the current.
Answer:
The movement of polar bears help figure out the impact of global warming in the arctic. Since polar bears travel over the frozen ocean they are able to determine the rate it melts as the bears retreat inland. The worse global warming become the quicker it becomes hotter in the arctic which is bad by the way.
Explanation:
The height of the tomato in air after 2.1 seconds is 78.31 m.
<h3 /><h3>What is height?</h3>
Height can be defined as vertical distance either between the top and bottom of something or between a base and something above it.
To calculate the height of the tomato after 2.1 seconds, we use the formula below.
Formula:
- H = ut+gt²/2............. Equation 1
Where:
- H = Height of the tomato
- u = Initial velocity = 27 m/s
- g = Acceleration due to gravity = Constant = 9.8 m/s²
- t = 2.1 seconds
Substitute these values into equation 1
- H = (27×2.1)+(9.8×2.1²)/2
- H = 56.7+21.609
- H = 78.31 m
Hence, the height of the tomato after 2.1 seconds is 78.31 m.
