Answer:
t = 1.05 s
Explanation:
Given,
The distance between your vehicle and car, 100 ft
The constant speed of your vehicle, u = 95 ft/s
Since, the velocity is constant, a =0
If the car stopped suddenly, time left for you to hit the brake, t = ?
Using the second equation of motion,
S = ut + ½ at²
Substituting the given values in the equation
100 = 95 x t
t = 100/95
= 1.05 s
Hence, the time left for you to hit the brakes and stop before rear ending them, t = 1.05 s
Answer: The answer to the question "what works all the time but never sleeps" can vary depending on the context or interpretation. Here are a few possible answers:
Explanation:
1. A machine or technology: Machines such as computers, servers, or automated systems can work continuously without needing sleep. They can perform tasks, process information, or operate machinery 24/7.
2. The human brain: While humans do need sleep for rest and rejuvenation, the brain never stops working. Even during sleep, the brain continues to regulate bodily functions, process information, and even dream.
3. Nature: The natural world is constantly active and functioning. For example, plants continue to photosynthesize, animals continue to move and hunt, and ecosystems continue to interact and evolve, even during the night.
4. Time: Time is always progressing and never stops. The concept of time keeps working, and events and processes occur continuously, regardless of day or night.
These are just a few possible answers. The correct response may depend on the specific context or intended interpretation of the question.
Answer: A man
Explanation:
A man works all day and never gets the chance to sleep.
B Radiation
C Conduction
D Convection
Answer:
thermal energy
Friction does negative work and removes some of the energy the person expends and converts it to thermal energy. The net work equals the sum of the work done by each individual force. The forces acting on the package are gravity, the normal force, the force of friction, and the applied force.
Explanation:
Answer:
Explanation:
Thermal energy due to heat coming in from rubbing like rubbing your hand and it feel warm
Answer:
A) equal to
In a closed system, the total energy prior to an energy transformation is equal to the total energy after.
Explanation:
A closed system is defined as an isolated region surrounded by a boundary across which no transfer of matter or energy can take place.
Hence, even if there is an energy transformation in a closed system, the overall energy of the closed system remains constant.
The lithosphere is made up of the Earth's crust and the upper part of the mantle. It is responsible for the formation of landforms like mountains and plateaus.
The lithosphere is made up of the Earth's crust and the upper part of the mantle. The Earth's crust is divided into several tectonic plates that float on the semi-fluid asthenosphere underneath. This rigid lithosphere is responsible for the formation of landforms like mountains, valleys, and plateaus.
