Explanation:
It is given that,
Mass of a bungee jumper is 65 kg
The time period of the oscillation is 38 s, hitting a low point eight more times.It means its time period is
After many oscillations, he finally comes to rest 25.0 m below the level of the bridge.
For an oscillating object, the time period is given by :
k = spring stiffness constant
So,
When the cord is in air,
mg=kx
x = the extension in the cord
So, the unstretched length of the bungee cord is equal to 25 m - 5.6 m = 19.4 m
The mass of the object will remain the same rather it's on the moon or on the Earth and even in other places. But the weight will change on the moon, so its weight will be different from the one it had on Earth
Balanced. They’re equally as strong so as their arm wrestling, neither of the men’s hands go down. Because they’re equally/balanced as strong.
It is a reactant, as it, with water and CO2 reacts to form the products.
420 m of total distance is covered by the skier on travelling from A to D.
Explanation:
As from the picture, it can be seen that first the skier moved from position A to position B. And the distance covered by this movement is 180 m. Then as the skier travels from position B to position C, the distance between these two positions is 140 m from the figure. As distance is a scalar quantity, the direction is not taken into consideration. So only the magnitudes of the distance between those points are added.
Now, the distance between A to B is 180 m and then from B to C is 140 m, atlast from C to D, the distance is given as 100 m.
So, the total distance will be the sum of all the above found distances. Thus, the total distance will be 180+140+100 = 420 m.
As the question is about distance, so no need to write the direction for it.
Thus, the final answer will be 420 m of total distance is covered by the skier on travelling from A to D.
