A football is kicked with a velocity of 18 m/s at an angle of 20. What is the balls acceleration in the horizontal direction as it flies through the air

Answers

Answer 1
Answer: If we perform all of our experiments on Earth and ignore
air resistance, then vertical acceleration is always 9.8 m/s²
downward, and horizontal acceleration is always zero.
Answer 2
Answer:

My apex test just corrected my original answer of 9.8 m/s^2 to 0 m/s^2.

Imagine that a tank is filled with water. The height of liquid column is 7 meters and the area is 1.5 square meters (m2). What's the force of gravity acting on the column of water?

Answers

-- The volume of water is    (1.5 m² x 7 m)  =  10.5 m³

   10.5 m³  =  10,500 liters

   Water mass  =  (10,500 liters) x (1 kg/liter) = 10,500 kg.

-- "Force of gravity on the water"

    =  Weight of the water = (10,500 kg) x (9.8 m/s²) = 102,900 newtons

-- Pressure on the bottom of the tank =

                 (102,900 newtons) / (1.5 m²)

             =      68,600 nt/m²  =  68,600 pascal .

your answer is 102,900 N

Which term refers to the time interval between the passage of successive wave crests? a. wave height
b. wave period
c. wave speed
d. wavelength

Answers

I believe the correct answer from the choices listed above is option B. The term that refers to the time interval between the passage of successive wave crests would be wave period. It is the time for a particle on a medium to make one complete vibrational cycle. 

a boy runs from his house to school at speed 5m/s on a straight road and returns with speed of 10m/s.The distance between the house and school is 100m. Find his average velocity.... with explaination please​

Answers

Explanation:

time spent to run from house to school=100/5=20s

time spent to return from school=100/10=10s

average velocity=200m/(10+20)

A kite suspended in the sky is flowing back and forth. Which type of friction is being described?

Answers

The type of friction of a kite suspended in the sky that is flowing back and forth is fluid friction. The fluid here is the air that helps the kite move back and forth. The kite feels a drag force due to air which acts in the upward direction.

Answer:

Fluid friction - in fluid friction, there is something called air resistance. This makes fluid friction happen in liquids AND in gases.

Explanation:

Which one is having lesser ressistance. a 60w bulb or a 40w bulb?

Answers

Power dissipation = (voltage across the component)² / (resistance of the component)

Since the resistance is in the denominator of the fraction in this formula for the
quantity of power dissipated, you can see that when the supply voltage is constant,
the smaller resistance dissipates more power.

So the 60w bulb has lower resistance than the 40w bulb.
