Henrietta is going off to her physics class, jogging down the sidewalk at a speed of 2.70 m/s. Her husband Bruce suddenly realizes that she left in such a hurry that she forgot her lunch of bagels, so he runs to the window of their apartment, which is a height 36.5 m above the street level and directly above the sidewalk, to throw them to her. Bruce throws them horizontally at a time 4.00 s after Henrietta has passed below the window, and she catches them on the run. You can ignore air resistance. Wit what initial speed must Bruce throw the bagels so Henrietta can catch them just before they hit the ground? Where is Henrietta when she catches the bagels?

What is the difference in electrical potential energy between two places in an electric field?a. current
b. resistance
c. potential difference
d. induction

Answers

The question is poorly worded, and makes it harder for the student to learn the basics of the subject. "Potential Difference" is the difference in electrical potential between two places in an electric field ... not in electrical potential energy.

How many times can disposable gloves be worn before being discarded?

Answers

Final answer:

Disposable gloves are designed for single use and should be discarded after each task to prevent cross-contamination or reduced effectiveness from damage. They should not be reused.

Explanation:

In general, disposable gloves are designed to be used once and then thrown away. They should be removed and discarded after handling a task, then a new pair of gloves should be worn for a different task. This is because reusing disposable gloves can lead to cross-contamination or the gloves becoming less effective if they become damaged from continuous use. For instance, if a person wears the same gloves while treating a patient and then handling medical equipment, bacteria and other harmful substances can spread, creating a risk to health. Therefore, it is crucial to practice accurate and responsible use of disposable gloves in healthcare settings and other scenarios where gloves are required for safety and hygiene purposes.

When a craton is exposed at earth's surface, it is called a ________. when a craton is exposed at earth's surface, it is called a ________. caldera continental shield mid-ocean ridge plate transform fault region?

Answers

When a Craton is exposed at earth's surface, it is called a continental shield. Continental shield is any of the large stable areas of low relief in the Earth's crust that are composed of Precambrian Crystalline rocks. Shield areas are regarded as continental nuclei, the observation often being made that most continental shields are bordered by belts of folded rocks of post-Precambrian age.

The tendency of an object to resist any change in its motion is known as?

Answers

Answer:

Inertia

Explanation:

The tendency of an object to resist any change in its motion is known as its inertia. The first law of motion is also known as the law of inertia. The inertia of an object can change its speed and the direction of motion. It is related directly to the mass of an object.

A body having more mass will have more inertia while a body having less mas will have less inertia.
It's inertia. A rule that you see every day, for example a brick will stay in the same spot unless a force acts on it.
