Considering that the grasshopper starts on the ground and lands on the ground, there is no change in elevation. The range of the grasshopper is given by: <span>R=<span><span><span>v2</span>sin2θ</span>g</span></span>
If we now take the information that this is a maximal distance, the maximum range is given when the angle of launch is 45 degrees. This yields the equation: <span><span>R<span>max</span></span>=<span><span>v2</span>g</span></span>
We know R_max=0.4 m and g=9.8 m/s^2, so we can solve for v: <span>v=1.98m/s</span>
We are asked for the horizontal component, which by trigonometry is: <span><span>vx</span>=vcosθ</span>
We again take our angle of launch as 45 degrees and arrive at: <span><span><span>vx</span>=1.40m/s</span></span>
H = 2.80t^3
h = 2.80 (1.55)^3 = 10.43
10.43 = 1/2 gt^2
10.43 x 2/9.8 = t^2
t = √2.12
= 1.45
Hope this helps
Explanation:
It is given that,
Diameter of the circular loop, d = 1.5 cm
Radius of the circular loop, r = 0.0075 m
Magnetic field,
(A) We need to find the current in the loop. The magnetic field in a circular loop is given by :
I = 32.22 A
(b) The magnetic field on a current carrying wire is given by :
r = 0.00238 m
Hence, this is the required solution.
Answer:
Turbine
Explanation:
Most of U.S. electricity generation is from electric power plants that use a turbine or similar machine to drive electricity generators. A turbine converts the potential and kinetic energy of a moving fluid (liquid or gas) to mechanical energy.
