Answer
When a body moves in projectile motion it has two components. One of the components is a horizontal component of the velocity and another is a vertical component.
The velocity along the horizontal component does not change because there is no acceleration long horizontal component.
Whereas velocity along vertical direction keeps on changing because the acceleration due to gravity is acting on the object. At a maximum height of the projectile velocity is equal to zero.
Answer:
Explanation:
Hello.
In this case, since the velocity is computed via the division of the distance traveled by the elapsed time:
The distance is clearly 1743 km and the time is:
Thus, the velocity turns out:
Which is a typical velocity for a plane to allow it be stable when flying.
Best regards.
Answer:
The sea level could have been much higher in the past.
Explanation:
The tectonic plates shifted and the mountain rose from there.
1). Wind more turns of wire in the coil around the core.
2). Increase the electrical current flowing in the wire.
(You can do that by using a battery or power supply with a little more voltage.)
3). If the core of the electromagnet is anything else but pure iron,
take it out, throw it away, and replace it with a core of pure iron.
Answer:
B ) the temperature of liquid water rises and falls slowly.
Explanation:
The specific heat of water is very high so for a given gain of heat , water will gain relatively less temperature . So it will not warm up easily and as a result of it , it will remain cool in spite of surrounding remaining warm. Water has therefore great moderating effect .
