A water balloon is launched with a speed of 40 m/s at an angle of 60 degrees to the horizontal. What is the vertical component of the velocity? a 40 m/s
b 34.6 m/s
c 0 m/s
d 20 m/s
Answers
Vertical component = 40 m/s x sin(60) = 34.6 m/s
Answer: b. 34.6 m/s
The vertical component of velocity is approximately 34.64 m/s. Therefore option B is correct.
When an object is launched at an angle, its velocity can be divided into horizontal and vertical components. The vertical component is found by multiplying the initial velocity by the sine of the launch angle.
To find the vertical component of the velocity, we use trigonometric relationships based on the given launch angle of 60 degrees and initial velocity of 40 m/s.
The vertical component can be calculated as
, where v is the initial velocity and
is the launch angle.
Calculation:
Given:
Initialvelocity (v) = 40 m/s
Launch angle = 60 degrees
Vertical component:
In this case, with an initial velocity of 40 m/s and a launch angle of 60 degrees, the vertical component of velocity is approximately 34.64 m/s (option b).

How are moving pulleys different from fixed-position pulleys? (Points : 3) Moving pulleys have more force than fixed-position pulleys. Moving pulleys are easier to use than fixed-position pulleys. Moving pulleys are attached to the object and move with the object. Fixed-position pulleys are connected to a fixed point and do not move. Moving pulleys are attached to the object and are stationary. Fixed-position pulleys are connected to a fixed point and move freely.

Answers
Answer:
Ice is water in solid phase, in this phase, the particles are very close together and relatively in fixed positions.
As the temperature starts to increase (thermal energy), also does the kinetic energy of the particles (so we have a change from thermal energy to kinetic energy), so they start to move "more", and the position of the particles starts to be less "fixed". There is a point where the particles have enough energy, and this point is where the phase of the water changes from solid to liquid phase (the fusion point). After this point the water can not hold his shape, and takes the shape of the container where it is.

Surface winds on Earth are primarily caused by differences in Air density due to unequal heating of Earth's surface. The answer is letter A. Surface currents are driven by winds that blow in certain patterns. They are caused by the Earth’s spin and the Coriolis effect. Evaporation adds water to the atmosphere. It is the change from liquid to gas wherein liquid molecules tends to go the gas phase and increases the number of molecules.
Explanation:
Causes of Different Pressure on the Earth's Exterior. Differences in pressures across the cover of the Earth are fundamentally produced by irregular heating of the surface by the Sun.
Final answer:
Surface winds on Earth are primarily caused by differences in air density due to unequal heating of Earth's surface. The Hadley circulation and the Coriolis effect influence the direction and patterns of these winds.
Explanation:
Surface winds on Earth are primarily caused by differences in air density due to unequal heating of Earth's surface. When the sun's rays hit the equator, the air at this latitude becomes heated and rises, creating an area of low pressure. This causes air from cooler, higher pressure areas to flow towards the equator, resulting in surface winds.
This circulation pattern is known as the Hadley circulation and is responsible for the trade winds, which blow from east to west near the equator. Similarly, the temperature differences between the poles and the equator create the polar easterlies and the prevailing westerlies.
As the Earth rotates on its axis, the Coriolis effect comes into play, causing the wind to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This is why trade winds blow from east to west and prevailing westerlies blow from west to east.

Answer: 54 miles in 1hr 30min
Explanation:
The train travels at a constant speed of 36 miles per hour. To find out how far it can travel in 1 hour 30 minutes, we need to convert the time to hours. Since there are 60 minutes in 1 hour, 1 hour 30 minutes is equal to 1.5 hours (1 hour + 30 minutes/60 minutes). To calculate the distance traveled, we multiply the speed of the train (36 miles per hour) by the time it travels (1.5 hours). So, the train can travel 36 miles per hour * 1.5 hours = 54 miles in 1 hour 30 minutes. Therefore, the train can travel a distance of 54 miles in 1 hour 30 minutes

Answer:
B) The larger one accelerates at 3.33 m/s² while the smaller one accelerates at 100 m/s².
Explanation:
Parameters given:
Mass of larger asteroid = 3000 kg
Mass of smaller asteroid = 100 kg
Force of collision = 10000 N
Since both of them experience the collision force, we can find how that force causes them to accelerate by using the formula of force:
F = m*a
=> a = F/m
For the larger one,
a = 10000/3000 = 3.33 m/s²
For the smaller one,
a = 10000/100 = 100 m/s²
F = M A
A = F / M
If a 10,000N net force acts on a 3,000 kg object, then the object's
acceleration is (10,000N / 3,000kg) = 3-1/3 m/s² for as long as the
force on it persists, and zero after that.
If a 10,000N net force acts on a 100 kg object, then the object's
acceleration is (10,000N / 100kg) = 100 m/s² for as long as the
force on it persists, and zero after that.
Those appear to be the numbers in choice-b, but the description
of the event and the situation is misleading.
