Answer:

Total distance

L = 39 km

total displacement

d = 29.1 km

Explanation:

Total distance moved by the car is total path length of the car

L = L_1 + L_2 + L_3

L = 20 + 13 + 6

L = 39 km

now similarly we will have

total displacement of the car towards East

x = 20 + 6 = 26 km

total displacement of the car towards South

y = 13 km

now net displacement of the car is given as

d = \sqrt{13^2 + 26^2}

d = 29.1 km

The equation for the de Broglie wavelength is: 
<span>λ = (h/mv) √[1-(v²/c²)], </span>
<span>where h is Plank's Constant, m is the rest mass, v is velocity, and c is the velocity of light in vacuum. However, if c>>v (and it is, in this case) then the expression under the radical sign approaches 1, and the equation simplifies to: </span>

What factors affect water quality?
JulsSmile [24]

Answer:

Explained below:

Explanation:

Water quality is determined in terms of the physical, chemical and biological content of water. The quality of water of lakes and rivers variates with the seasons and also geographic areas, still in the absence of pollution. There are  so many factors  which affect water quality are as follows :

Pesticides

Temperature

Runoff

Sedimentation

Erosion

pH

Dissolved oxygen

Pesticides

Litter and rubbish

Decayed organic materials

Toxic and hazardous substances

Oils, grease, and other chemicals

A batter hits a 0.140-kg baseball that was approaching him at 19.5 m/s and, as a result, the ball leaves the bat at 44.8 m/s in
Arada [10]

Answer:

5295.3 N

Explanation:

According to law of momentum conservation, the change in momentum of the ball shall be from the momentum generated by the batter force

mv + P = mV

P = mV - mv = m(V - v)

Since the velocity of the ball before and after is in opposite direction, one of them is negative

P = 0.14(44.8 - (-19.5)) = 9 kg m/s

Hence the force exerted to generate such momentum within 1.7ms (0.0017s) is

F = P/t = 9/0.0017 = 5295.3 N
