# What does a low order explosive material resemble when exposed?

## What does a low order explosive material resemble when exposed?

What substance does a low-order explosive resemble when exposed to air and sunlight? dark brown rocks.

## What causes greatest damage in an explosion?

Blast Effects Most damage comes from the explosive blast. The shock wave of air radiates outward, producing sudden changes in air pressure that can crush objects, and high winds that can knock objects down. For the most part, a nuclear blast kills people by indirect means rather than by direct pressure.

## What factors affect how far a projectile will land?

Figure 1: Trajectory Plot for Angled-Launched Projectiles During its flight through the air, the horizontal speed of the projectile remains constant; the vertical speed changes due to gravity. The horizontal distance depends on two factors: the horizontal speed (vox) and the time the projectile has been in the air.

## At what angle range will be maximum?

Answer: The textbooks say that the maximum range for projectile motion (with no air resistance) is 45 degree.

## Why mass does not affect projectile?

Mass does not affect the speed of falling objects, assuming there is only gravity acting on it. Both bullets will strike the ground at the same time. The horizontal force applied does not affect the downward motion of the bullets — only gravity and friction (air resistance), which is the same for both bullets.

## How does angle affect distance?

Launch angle trajectory comparisons The launch angle determines the maximum height, time in the air, and maximum horizontal distance of the projectile.

## Why is a 45 degree angle the best trajectory?

As ball speed increases, so does the drag force and the lower is the required launch angle. A launch at 45 degrees would allow the ball to remain in the air for a longer time, but it would then be launched at a lower horizontal speed at the start and it would slow down more because of the longer flight time.

## At what angle of projection horizontal range is maximum?

Hence, at θ=45o , Range is maximum.

90 o

45 degrees

## How far does a stone fall in 6 seconds?

The formula I learned in high school Physics is s=1/2gt squared, where s is distance in meters, g is the force of gravity (10 meters per second per second), and t is time in seconds. So in 6 seconds, a person will fall 5 x 36 or 180 meters.

## What launch angle do you think will yield the longest drive?

Everyone in freshman physics learns that the optimal launch angle for a projectile – the angle that makes a ball fly the farthest – is 45 degrees.

## Why doesn’t VX change as an object travels?

As you observed, the horizontal component of velocity (v) does not change as the object moves, but the vertical component (v) decreases over time. Set up Gizmo: Accelerationis a change in velocity. Both the banana and monkey undergo a downward acceleration due to the force of gravity.

## How do you find the optimal launch angle?

Since all paths meet at one point, we know we have found the launch angle for which the projectile’s horizontal path distance reaches a maximum. c = s 2hgv2 + v4 2agv2 + g2 . Recall c = v2/g cot✓m, so we find that the optimal initial angle, ✓m, is ✓m = arccot g v2 s2hgv2 + v4 2agv2 + g2 !

## Why do complementary angles have the same range?

They are equal because the sine value of 60 degrees is equal to the sine value of 120 degrees. Other complementary angles such as 20 degrees and 70 degrees will also confirm the equality of range 1 to range 2.

## At what angles ranges are equal?

The horizontal distance traveled by a projectile is called its range . A projectile launched on level ground with an initial speed v0 at an angle θ above the horizontal… will have the same range as a projectile launched with an initial speed v0 at 90° − θ.

## For which pair of angles is the range equal?

Horizontal range Horizontal range is same for a pair of projection angle. It means that the range of the projectile with a given initial velocity is same for a pair of projection angles θ and 90° – θ.

## What is complementary angle?

mathematics. : two angles that add up to 90 degrees.

## Which angle is complementary to 3?

In a right angled triangle, the two non-right angles are complementary, because in a triangle the three angles add to 180°, and 90° has already been taken by the right angle. When two angles add to 90°, we say they “Complement” each other.

## What is the complementary angle of 90?

Complementary angle of 90o is 0o and supplementary angle of 90o is 90o .

## How do you know if an angle is complementary or supplementary?

Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees.

## Can an angle be both complementary and supplementary?

Yes, because the sum of two angles is 180, and if they are both 90 degrees, they add up to 180, making them supplementary, and of the same measure, making them congruent.

## Is it true that if two angles are vertical then they are congruent?

Vertical angles are a pair of opposite angles created by intersecting lines. The Vertical Angles Theorem states that if two angles are vertical, then they are congruent.

## What does a complementary angle look like?

Two Angles are Complementary when they add up to 90 degrees (a Right Angle). They don’t have to be next to each other, just so long as the total is 90 degrees. Examples: 60° and 30° are complementary angles.
