Does It take 100 HP to lift a 1000 kg weight from ground to the 4th floor. True or False.

Answers

Answer 1

Answer:

Answer:NOPE you need more

Explanation:

The power required to lift a weight depends on the force needed and the speed at which the weight is lifted. The force required to lift a weight is given by the equation F = m * g, where m is the mass of the object and g is the acceleration due to gravity (approximately 9.81 m/s² on Earth).

For example, if a 1000 kg weight is lifted 10 m in 10 seconds, the work done can be calculated as W = (1000 kg) * (9.81 m/s²) * (10 m) = 98100 J (Joules). The power required is work done per unit time P = (98100 J) / (10 s) = 9810 W (Watts), which is approximately 9.8 kW¹.

In terms of horsepower, since 1 horsepower is approximately equal to 746 Watts¹, the power required would be about 13.15 horsepower. So, it does not require 100 horsepower to lift a 1000 kg weight from the ground under these conditions. However, these calculations assume ideal conditions and do not take into account factors such as air resistance or mechanical inefficiencies. In real-world applications, more power might be needed.

7.If your driver license is suspended, you may drive only:a. If you obtain an essential need driver license
b. If you have an accompanying licensed driver
c. If you drive on less traveled roads
d. If you get permission from the local police

Answers

You shouldnt drive under any circumstances and the answer would be d

Final answer:

When a driver's license is suspended, typically, one cannot drive. However, one might be able to drive under certain conditions, like obtaining an essential need driver license or a hardship license. Laws vary by location, hence local transportation operating rules must be consulted.

Explanation:

When your driver's license is suspended, under most jurisdictions you are generally not allowed to drive. However, there can be certain exceptions to this rule. The correct answer among the provided options would be (a) If you obtain an essential need driver license. This type of license, also referred to as a hardship or restricted license, may allow you to drive under certain conditions, for instance, for work or medical appointments. It's important to note that laws may vary by location, so it is always important to consult with local legal sources or transportation departments to understand specific regulations and processes related to obtaining conditional driving permissions when your license is suspended.

Dark spots on the photosphere are known asA. the corona.
B. the chromosphere.
C. sunspots.
D. solar wind.

Answers

The dark spots that are found on the photosphere are called sunspots. These are a temporary phenomena and are areas of different temperature compared to the surroundings. Sunspots are at a lower temperature compared to the surrpundings and they are created due to magnetic field flux. They can stay on from a few days to a few months and eventually decay.

a car traveling at 40m/s starts to decelerate steadily. it comes to a complete stop in 12 seconds. what is the acceleration?

Answers

Velocity - v =0 m/s,

initial velocity - v(0)= 40 m/s

a - acceleration,

time - t = 12 s.

v=v(0) - at

0 = 40m/s - a*12s

12a = 40

a = 3.3 m/s²
