Answer:
The correct answer is - radiant.
Explanation:
Electromagnetic waves are the transverse waves that get energy as radiation from the source and transfer to an absorber so, the radiant energy is the energy of electromagnetic waves.
Electromagnetic waves are can travel in space unlike mechanical waves and are made up of photons, tiny packets of energy. Electromagnetic waves or spectra include radio waves, infrared, light, microwaves, UV, X-rays, and gamma rays.
Answer:
41.8° to the vertical ( west of North) , 44.6 s
Explanation:
Using Pythagoras theorem, taking the direction it must go line as the hypotenuse
vh² = vs² + vd² vs is the speed of the stream, vh is the speed in the direction it must go to the vertical and vd is the speed going directly north
3 ² = 2² + vd²
9 - 4 = vd²
√5 = vd
2.24 m/s = vd which is the resultant speed
the direction it will go = tan θ = 2 / 2.24
θ = tan⁻¹(2 / 2.24) = 41.8° to the vertical ( west of North)
b)t = distance / v = 100 / 2.24 = 44.6 s
Answer:
Ficus trees are warm-weather, tropical trees. Varieties include the fruit-producing fig, the houseplant Ficus benjamina, and the rubber plant. Whether you grow ficus trees in the landscape or in the home, providing the right temperature is vital to prevent damage and ensure good, healthy growth on the tree.
Explanation:
initial velocity = 0 = v₍i₎
final velocity = ? = v₍f₎
t = 12 sec
Acceleration = 4m/s²
First we have to find the distance d, for this we use the
formula,
D = v₍i₎t + 1/2at²
D = 0(12) + ½ (4)(12)²
Distance = d = 288 m
Now to find the Vf use the formula,
V₍f₎² = v₍i₎² + 2ad
V₍f₎² = (0)2 + 2(4)(288)
V₍f₎² = 2304
V₍f₎ = 48 m/s
so the velocity at the end of 12 sec is 48 m/s
