Answer: The spring of the spring is 25 N/m.
Explanation:
Mass of the body = 25 g= 0.025 kg (1 kg = 1000 g)
Oscillation is 4 sec = 20
Oscillation in 1 sec =
Frequency of the vibration of the spring =
Force constant can be calculated bu using the relation between the frequency and, mass and spring constant 'k'
The spring of the spring is 25 N/m.
Answer:
The Surface heat flux is -9205 W/m^2
Explanation:
Explanation is in the following attachment
Answer:
d = 0.645 m <em>(assuming a radius of the ball bearing of 3 mm)</em>
Explanation:
<u>The given information is:</u>
<u>We need to assume a radius for the ball bearing, so suppose that the radius is 3 mm = </u>.
First, we need to find how many times the radius of the sun is bigger respect to the radius of the ball bearing, which is given by the following equation:
Now, we can calculate the distance from the center of the sun to the center of the sphere representing the earth, :
[tex] d_{s} = \frac{d_{e}}{r_{s}/r_{b}} = \frac{1.496 \cdot 10^{11} m}{2.32\cdot 10^{11}} = 0.645 m
I hope it helps you!
Answer:
a.) At their highest point, both of them have the same amount of mechanical energy.
Explanation:
Grasshopper A jumps upwards with speed v while grasshopper B jumps at an angle of 66 degree with horizontal at same speed
so vertical speed of B is given
So when both the grasshopper will jump upwards they both will attain different maximum heights
Since initial speed of both grasshopper is same so their mechanical energy is always conserved
So mechanical energy of grasshopper A is given as
Mechanical energy of grasshopper B is given as
So we have
a.) At their highest point, both of them have the same amount of mechanical energy.
