Answer:
150 km/hr²
Explanation:
The data for the motion of the train includes;
The train starts from rest, therefore, the initial velocity of the train, u = 0 km/hr
The speed of the train after 0.5 hours, v = 75 km/hr
The change in time during the motion of the train, Δt = 0.5 hours
The acceleration, 'a', is the rate of change of velocity with time;
Therefore, we have;
a = (75 km/hr - 0 km/hr)/(0.5 hr) = 150 km/hr²
a = 150 km/hr² = 150 km/hr² × 1,000 m/km × hr²/(3,600 s)² = 5/432 m/s²
The acceleration of the train, a = 150 km/hr² = 5/432 m/s².
Feeling slightly uncomfortable during exercise is completely normal and should be expected. If there is unbearable pain however, the exerciser should stop and consult a doctor.
I hope this helped!
<h3><u>Technology used by astronomers to look for life on other plants:</u></h3>
- Space-based Hubble and Spitzer telescopes and Green Bank telescopes are used.
- Many new satellites are launched to trace earth like planets. Even the telescopes are carried by spacecrafts.
- Astronomers are using Allen Telescope Array that comprises 42 radio antennas to get hold of signals over a wide range of radio frequencies that are tuned to listen to the regions nearer to the red dwarf star constellations.
- Scientists needed telescopes that are capable of detecting planets like Earth in our planet’s neighborhood and see if any biological signatures connected to any microbial or other intelligent life can be found.
- Radio signals are also being used to detect if the outside world has something to communicate so that they can be detected.
<h2>Answer:</h2>
The feature of an object affects its weight are given below
- mass of the object
- location of the object
- how much force Earth exerts on the object
<h2>Explanation:</h2>
Weight of the body is equal to the product of gravity and the mass of it so weight is dependent upon mass. The more the mass, the more is the weight. In the same way the location of the object differs if the location is far from the earth. Similarly gravity is the force with which earth attracts everything towards its center therefore we can say that if the object moves away from the earth center the weight decreases eventually..
