If your mass is 50 kg (you weigh 110 pounds), and the mass of the refrigerator
is 100 kg (it weighs 220 pounds), and you're standing so that the center of
the frig and the center of you are 1 meter apart (about 3 feet), then the force
of gravity between you and the frig is about 0.0000012 ounce. That's why.
Without the the water on earth, nothing would be alive, no cavemen, no dinosaurs. Water is one of the most important component on earth so people can live. Water is everywhere. It goes through river, mountains, lakes, oceans even if your house. Without water human kind and any other would not be alive.
To solve this problem we will apply the concepts related to the double slit-experiment. Under this concept we understand the relationship between the minimum angle, depending on the order of the fringes, the wavelength and the distance between slits. Therefore we have the following relation,
Here,
m = Order of the fringes
D = Distance between slits
= Wavelength
Replacing with our values we have,
Through the relationship between distances then we have that the basic amplification distance is given by the relationship between the distance of the slit L and the angle, then
Thus the width of the central maximum is
Therefore the widht is 0.466m
Answer:
1.76km
Explanation:
Here,
1mi = 1.6km
1.10 miles = 1.6 x 1.10 km
= 1.76 km
*Let north and east as positive direction.
1. a = +30 km / 2 hr
a = +15 km/hr
2. a = +45 km / 3 hr
a = +15 km/hr
3. a = -30 km / 1.5 hr
a = -20 km/hr
4. a = -25 km / 0.5 hr
a = -50 km/hr
speed = (15+15+20+50) / 4
= 25 km/hr
velocity:
(horizontal): (+15-50)= -35 km/hr
(vertical): (+15-20)= -5km/hr
v = sqrt(35^2 + 5^2)
v = 35.36 km/hr
