An object falls freely from height H. if it takes one second to travel last half of total displacement find height H priop to the fall.​

Answers

Answer 1
Answer:

Answer:9.82 m

Explanation:

As we know from equation of motion

S=v*t +0.5 a t^2

Know s=H/2

a =9.82

t=1

V=0

Plugging the values

H*0.5=0+0.5*9.82*1^2

H=9.82 m

If an object is to rest on an incline without slipping, then friction must equal the component of the weight of the object parallel to the incline. This requires greater and greater friction for steeper slopes. Show that the maximum angle of an incline above the horizontal for which an object will not slide down is θ.

_____________ was a popular technique used by animator, Tim Burton. With this animation technique, objects/puppets are made by the artist, and each time they are moved, the artist photographs them instead of drawing them.a. Cel animation
c. Projecting animation
b. Computer Generated Imagery
d. Stop motion animation

Answers

The correct answer is D. stop motion animation. It's called stop motion because you make an illusion of a motion by moving and stopping the characters and then reshooting. This is pretty common but takes a lot of time so not many people choose to do it. It also takes great skill to do it, not just patience.

Stop motion animation is the popular technique that is used by animator, where objects/puppets are made by the artist, and each time they are moved.

What is animation?

Animation can be regarded as a method whereby figures are been manipulated so as to appear as moving images.

One of the notable type of animation is Stop motion animation where the artist photographs the figure instead of drawing them.

One major cause of floods isA. rapid spring snowmelt.
B. light rain over a large area.
C. a decrease in stream discharge.
D. increased capacity of stream channels.

Answers

The correct answer is A. rapid spring snowmelt. When the spring times come, sometimes there's a lot of warmth that suddenly comes, especially nowadays when there's things such as global warming. So the snow melts and large amounts of water can flood the fields that are often found at the foot of a mountain or similar things.
The answer to this question is A. Rapid Spring Snowmelt. You can find the answer in Pearson Earth Science Part 1 Textbook. "A heavy downpour or rapid snowmelt can flood canyons with a mixture of soil, rock, and water." 

Hope this helps. Have a great day!

Briefly summarize how the pulleys worked with respect to changes in effort force and effort distance compared with resistance force and resistance distance what are the advantages of using pulleys what do you think would happen to the mechanical advantage if you needed a third movable pulley

Answers

A pulley is a wheel with two raised edges so that a rope or a string will run along the wheel. The effort force is the one where there is a weight attached to it and enables the pulley to work while the effort distance is the distance between the pulley and the weight attached.

A ball of clay sinks when placed in water. The same piece of clay floats if it is made into the shape of a boat.Why does the clay float when made into the shape of a boat?
a. The clay is less dense when stretched into the shape of a boat.
b. The buoyant force is greater on the clay when it has a spherical shape.
c. The boat shape displaces a greater volume of water than the ball shape.
d. The weight of the clay boat is less than the weight of the clay ball.

Answers

The correct answer is definitely d. The weight of the clay boat is less than the weight of the clay ball.
In such situations, the point that we should take as a basis to resolve a question is weight. If the weight of clay is less than that of a clay ball, the clay will float.

Answer:

c. The boat shape displaces a greater volume of water than the ball shape.

What type of interference results in beats?constructive
destructive
negligible
interference is not involved in the creation of beats

Answers

Answer: constructive

Explanation:

Two waves having slightly different frequencies when interfere constructively produce beats. Superposition of these two waves results in addition of amplitudes of the two waves. The amplitude of the resultant wave vibrates or beats.

Beat frequency is given by the absolute difference between the frequencies of the two waves.

b = |f₂ - f₁| = f₂ - f₁ or f₂ + f₁
The answer is A Constructive.
