Answer:
most of the time the bullet will not hurt you but sometimes can hurt or kill you.
Answer:
24.3 degrees
Explanation:
A car traveling in circular motion at linear speed v = 12.8 m/s around a circle of radius r = 37 m is subjected to a centripetal acceleration:
Let α be the banked angle, as α > 0, the outward centripetal acceleration vector is split into 2 components, 1 parallel and the other perpendicular to the road. The one that is parallel has a magnitude of 4.43cosα and is the one that would make the car slip.
Similarly, gravitational acceleration g is split into 2 component, one parallel and the other perpendicular to the road surface. The one that is parallel has a magnitude of gsinα and is the one that keeps the car from slipping outward.

Answer:
Radio waves are used for communications and radar. Microwaves are used to cook your food. Infrared waves are used in remote controls and are emitted from all warm objects, allowing them to be used to create heat-sensitive cameras.
Explanation:
Basically electromagnetic waves can be found in your everyday life.
Answer:
18 m, 7.9 m
Explanation:
In the y direction:
y = y₀ + v₀ᵧ t + ½ aᵧ t²
0 = 0 + (v₀ sin 45°) t + ½ (-g) t²
0 = t (v₀ sin 45° - ½ g t)
t = 0, t = 2v₀ sin 45° / g
In the x direction:
x = x₀ + v₀ t + ½ at²
x = 0 + (v₀ cos 45°) t + ½ (0) t²
x = v₀ cos 45° t
Substituting for t:
x = v₀ cos 45° (2v₀ sin 45° / g)
x = v₀² / g
When g = 9.80 m/s², x = 3.0 m:
3.0 = v₀² / 9.80
v₀² = 29.4
On the moon, when g = 9.80/6:
x = 29.4 / (9.80 / 6)
x = 18 m
As you can see, x is inversely proportional to g, so 1/6 the gravity means 6 times the distance. So on Mars:
x = 3 / 0.38
x = 7.9 m
