Describe the motion shown in the lines
Answer:
Solution
For figure (a)
During interval AB Velocity is +ve, so the particle is moving in +ve direction, but it is slowing down as acceleration (slope of v-7 curve) is negative.
During interval BC Particle remains at rest as the velocity is zero. Acceleration is also zero.
During interval CD Velocity is -ve, so the particle is moving in -ve direction and is speeding up as acceleration is also negative.
For figure (b),
During interval AB Particle is moving in +ve direction with constant velocity and acceleration is zero.
During interval BC Particle is moving in +ve direction as velocity is +ve, but it slows down until it comes to rest as acceleration is negative.
During interval CD Velocity is -ve so the particle is moving in -ve direction and is speeding up as acceleration is also negatived

The integumentary system is an organ system consisting of the skin, hair, nails, and exocrine glands. The skin is only a few millimeters thick yet is by far the largest organ in the body. The average person’s skin weighs 10 pounds and has a surface area of almost 20 square feet. Skin forms the body’s outer covering and forms a barrier to protect the body from chemicals, disease, UV light, and physical damage. Hair and nails extend from the skin to reinforce the skin and protect it from environmental.

The system covers and protects the tissues of the body from UV light and from infections due to bacteria and viruses is - the integumentary system,
The integumentary system is the outer covering of the body that is made up of the skin with other outer structures such as nails, and hairs. The integumentary system has several functions in the body.
It protects the body internal organs from infection from viruses and bacteria. It avoids dehydration.secrete oils that enhances the barrier function of the skin from UV radiation from the sun.provide the first line of defense against infection. sweat glands present on skin help in thermoregulation. produce vitamin D from by sun exposure by cholesterols. neurons imbedded on the integumentary layer to sense the outside world.Thus, the correct answer is - the integumentary system

which of these actions has contributed to the increase of greenhouse gases in the atmosphere?
A) Clearing forests
B) Excessive planting
C) Chopping wood
D) Watering crops
Answer:
A
Explanation:
Trees and other plants absorb carbon dioxide from the atmosphere as they grow. This is converted into carbon and stored in the plant's branches, leaves, trunks, roots and in the soil. Cutting down of trees without allowing them to regrow, the carbon stored is released to the atmosphere in form of carbon dioxide which contributes to as much as 30 percent of global greenhouse-gas emissions.
