Answer:

When drawing free-body diagrams, each force is represented by an arrow (a vector). The size of the arrow shows the relative magnitude of the force, while the direction the arrow is pointing tells us in which direction the force is acting

An amateur player is about to throw a dart with an initial velocity of 15 meters/second onto a dartboard that is at a distance o
Minchanka [31]

Answer:

B. 0.16 m

Explanation:

The vertical distance by which the player will miss the target is equal to the vertical distance covered by the dart during its motion.

Since the dart is thrown horizontally, the initial vertical velocity is zero:

v_y = 0

While the horizontal velocity is

v_x = 15 m/s

The horizontal distance covered is

d_x = 2.7 m

Since the dart moves by uniform motion along the horizontal direction, the time it takes for covering this distance is

t=\frac{d_x}{v_x}=\frac{2.7 m}{15 m/s}=0.18 s

along the vertical direction, the motion is a uniformly accelerated motion with constant downward acceleration g=9.8 m/s^2, so the vertical distance covered is given by

d_y = \frac{1}{2}gt^2=\frac{1}{2}(9.8 m/s^)(0.18 s)^2=0.16 m

An FM radio station transmits a signal with a frequency of 89.1 MHz. Give the wavelength in meters. (use at least three signific
STALIN [3.7K]

Answer:

3m

Explanation:

89.1 MHz means

89.1×10^6 cycles/second.

Electromagnetic radiation (including radio waves) travel at

3.0×10^8meters/second

Wavelength = Speed/Frequency

The wavelength of a

89.1MHz radio signal is

3.0×10^8/89.1x10^6

= 0.03x10^2

= 3meters
