There are several formulas that describe the distance, speed, and time for
a falling body. The one I use the most happens to be the one that'll be the
most useful to solve this problem:
Distance = 1/2 g t²
We know the distance and we know ' g ', so we can use
this formula to find ' t '.
Distance = (1/2) (gravity) (time)²
(239 m) = (1/2) (3.7 m/s²) (time)²
Divide each side
by 1.85 m/s² : (129 m) / (1.85 m/s²) = (time)²
(129/1.85) sec² = (time)²
Take the square root
of each side: 8.35 sec = time
Answer:
64°
Explanation:
The triangle is an isosceles triangles (both legs are equal to the radius of the circle), so that means the base angles are the same.
Angles of a triangle add up to 180°, so:
128 + 2x = 180
2x = 52
x = 26
∠1 is complementary to the base angle, so:
∠1 = 90 − 26
∠1 = 64
In Medicine, "etiology" means the origin or cause of a disease.
Similar to Hippocrates, modern scientists who study etiology believe that diseases come from natural causes such as bites from infected insects.
Answer:
0.084 kg
Explanation:
I = 0.80 N-s (East wards) = 0.80 i N-s
u = 3.8 m/s = - 3.8 i m/s
v = 5.7 m/s = 5.7 i m/s
Let m be the mass of bat.
I = m (v - u)
0.8 i = m ( 5.7 i + 3.8 i)
0.8 i = m x 9.5 i
m = 0.084 kg
Answer:
Gravity changes with altitude. as we know The gravitational force is proportional to 1/R2, where R is your distance from the center of the Earth.
eg. The radius of the Earth at the equator is 6400 kilometers.
Let's say you were in a jet at the equator that was 40 kilometers high above the earth's surface.
