Answer:

False

Explanation:

Answer:

b and f

Explanation:

Following are examples of projectile motion: a. A tennis ball lobbed over a net c. A plastic disk sailing across a lawn d. A hawk diving to catch a mouse e. A parachutist drifting to Earth. The correct options are A, C, D and E.

Projectile motion refers to the motion of an object that is launched into the air and moves along a curved trajectory under the influence of gravity alone, with no other forces acting horizontally. In projectile motion, the object follows a path called a parabola.

In the given options, a tennis ball being lobbed over a net, a plastic disk sailing across a lawn, a hawk diving to catch a mouse, and a parachutist drifting to Earth all demonstrate projectile motion. In each case, the objects are initially launched or propelled into the air and subsequently follow a curved path influenced primarily by gravity. The trajectory of these objects can be described by a parabolic shape, which is a characteristic of projectile motion.

The correct options are A, C, D and E.

I think it would be, D. Warm air in a hot air balloon rises and heats air at the top of the  balloon.

The scenario that represents an example of the transfer of thermal energy by convection is the warm air in a hot air balloon rises and heats air at the top of the balloon. Thus, the correct option for this question is D.

Convection may be defined as a type of process through which heat is significantly transferred by the movement of a heated fluid such as air or water. It involves the transfer of heat by the movement of a fluid (liquid or gas) between areas of different temperatures.

Thermal energy refers to the energy which is contained within a system that is responsible for its temperature. Heat is the flow of thermal energy.

This thermal energy gets transferred through the process of convection from the top of the balloon in an example of a hot air balloon. The concept of this works on the warm air that is filled in a balloon and this warm air rises and heats air at the top of the balloon.

Therefore, the correct option for this question is D.

Answer: When work is positive, the environment does work on an object

Explanation:

The correct option is a)When work is positive, the environment does work on an object.

If work is done on the system , positive work is done on the system because energy enters the system in case of positive work done .If work is done by the system , work done will be negative

According to work energy theorem , change in kinetic energy is equal to work done . when energy enters in the system that means final energy is greater than the initial energy of the system , which implies positive work is done on an object .

this implies , correct option is a)When work is positive, the environment does work on an object.

Answer B. the direction of force is the same

Answer:

Tiny particles in solids, liquids and gases are always in motion. It is the motion of particles that creates a form of energy called thermal (heat) energy that is present in all matter. The particles in solids are tightly packed and can only vibrate. Matter in its solid state has the lowest amount of thermal energy (for that type of matter). Because solids have less thermal energy than liquids or gasses, the atoms in their solid state move very little.

7. B) Electrons from your hair jump to the balloon, causing it to become negatively charged on one side.

Explanation:

The ACTUAL answer

1. Ruth first gained fame as a pitcher.

Although best remembered for swatting a prodigious 714 home runs and slugging .690, which remains a major-league record, Ruth was one of baseball’s most dominant left-handed pitchers in the 1910s. He won 89 games in six seasons with the Boston Red Sox, including 24 in 1917, and helped the team win three World Series titles. Ruth only pitched five games for the New York Yankees as his position switched to outfielder after being sold by Boston before the 1920 season.

2. He did not retire as a New York Yankee.

Ruth’s major-league career not only started in Boston, it ended there as well, but not with the Red Sox. Discarded by the Yankees as his performance waned, Ruth signed with the National League’s Boston Braves in 1935 in the hopes of becoming the team’s manager the following season. When it became clear that his skills had deteriorated and the promise would not be kept, Ruth ended his 22-year career after just 28 games in a Braves uniform.

3. Ruth was not a unanimous choice for the Baseball Hall of Fame.

A year after his retirement, Ruth was among the five initial inductees elected to the new National Baseball Hall of Fame under construction in Cooperstown, New York. In spite of Ruth’s amazing career statistics, 11 of the 226 voters left him off their ballots, and the “Sultan of Swat” trailed Ty Cobb as the leading vote-getter. Ruth’s plaque in Cooperstown refers to him as baseball’s “greatest drawing card,” and proving the point, the Hall of Fame last month opened a new exhibit on Ruth to coincide with the centennial of his first big-league season.

Explanation:

Answer:

He began his career as a pitcher: Ruth was both a left-handed pitcher and left-handed batter.

His father died in a fight with a family member

Ruth played for the Boston Red Sox (1914-1919), the New York Yankees (1920-1934) and briefly the Boston Braves (1935).
