Force of air and gravitational force are acting on the ball when launched from the slingshot.

When a ball is launched from a slingshot, during its travel force of air as well as gravitational force are acting on the ball because there is air which moves opposite to the motion of a ball whereas the force of gravity attracts the ball downward.

The force of air slows down the motion of the ball while on the other hand, the force of gravity brings the ball to the ground due to attraction. If these two forces are not present then the ball continues its motion forever so we can conclude that force of air and force of gravity are acting on the ball when launched from the slingshot.

Explanation:

Answer:

Journey A average speed is 19.86 meters per second

Journey B average speed is 13.68 meters per second

Explanation:

The average speed is defined as the distance divided by the time, so that's what we have to do. But first, let's convert the time in seconds and the distance in meters, because we have to answer in meters per second:

Journey A:

2 hours = 120 minutes. Each minute have 60 seconds, so 120•60= 7200 seconds.

143 km = 143000 meters

143000/7200 = 19.86 m/s

Journey B:

3 hours = 180 minutes + 15 minutes = 195 minutes

195•60 = 11700 seconds

160 km = 160000 meters

160000/11700 = 13.68 m/s

The number of heaters that can safely be operated in the circuit is 5 heaters.

From the question given above, the following data were obtained:

Power of heater = 300 W

Voltage (V) = 110 V

Current (I) = 15 A

Voltage (V) = 110 V

Current (I) = 15 A

P = IV

P = 15 × 110

Thus, the power that can be drawn from the circuit is 1650 W

Power of heater = 300 W

Answer:

Having more plants performing photosynthesis could help reduce the amount of carbon dioxide in the atmosphere.

Explanation:

sample answer

The plants can be used in the future to help counteract some human

emissions they absorb carbon dioxide from the air and release oxygen.

It is a process carried out by photosynthetic autotrophic organisms, such as plants, algae and some prokaryotes. These organisms capture sunlight, convert it into chemical energy, which will be used to produce organic compounds, based on water and carbon dioxide.

Trees, like other plants, in the process called photosynthesis, absorb carbon dioxide from the air and release oxygen. They also make the air wetter and cooler. In this way, plants contribute to the good quality of the air we breathe.

According to the conservation of angular momentum, if the moment of inertia increases, the angular velocity must DECREASE.

Answer:

scientists often prefer to measure mass rather than weight because weight is affected by gravity while mass is not. Mass is always the same.

Explanation:

Weight is a force rather than a measure of the amount of matter something contains. The same amount of matter can have different weights depending on where it is. Mass directly measures the amount of matter present and remains the same no matter where it's measured.

No

The rate of diffusion defines the gas that passes through some area over the course of time.

Answer:

Explanation:

The electromagnetic force, also called the Lorentz force, acts between charged particles, like negatively charged electrons and positively charged protons. Opposite charges attract one another, while like charges repel. The greater the charge, the greater the force.

This question involves the concepts of centripetal force and centripetal acceleration.

a) The centripetal acceleration for the piece of gum stuck to the outside edge of the record will be "6.67 m/s²".

b) The gum will have to overcome "0.033 N" centripetal force to remain stuck to the vinyl.

a)

The centripetal acceleration of the gum can be found using the following formula:

[tex]a_c=\frac{v^2}{r}[/tex]

where,

[tex]a_c[/tex] = centripetal acceleration = ?

v = linear speed of record = 1 m/s

r = radius of the record = [tex]\frac{diameter}{2}=\frac{0.3\ m}{2}=0.15\ m[/tex]

Therefore,

[tex]a_c=\frac{(1\ m/s)^2}{0.15\ m}\\\\a_c = 6.67\ m/s^2[/tex]

b)

Now, the centripetal force can be given as follows:

[tex]F_c=ma_c\\F_c=(0.005\ kg)(6.67\ m/s^2)\\F_c=0.033\ N[/tex]
