False, friction, air resistance and gravity will be acting on it
We can look at all the ages of the earth since it’s a big crack is reveals many layers of the earth and we can know about chemicals and metals that were in earth and diffrent times
The answer is actually True, I just took the test and it was correct.
Answer: current = 10.25A
Explanation:
Toward = 240w
Alarm clock = 30w
Tanning bed = 720w
4 60 watts bulb = 60 * 4 = 240w
Total power = 240 + 30 + 720 + 240 = 1230w
Voltage = 120v
Recall that Power = current * voltage
1230 = current * 120
current = 1230/120 = 10.25A
An object thrown in air moving under the influence of gravitational force is known as projectile.
The projectile is thrown with an initial velocity at an angle with the horizontal. The initial velocity can be resolved in to horizontal and vertical components.
Here,
is the horizontal component of initial velocity,
is the initial velocity of the projectile, and
is the angle by which the projectile is thrown with respect to the ground.
The vertical component of initial velocity of the projectile is,
Here,
is the vertical component of initial velocity.
At maximum height the vertical velocity of the projectile momentarily goes to zero.
To calculate the time for maximum height is,
Here,
is the velocity of the projectile at maximum height, g is the acceleration due to gravity, and
is the time for maximum height reached by the projectile.
Substitute
The vertical velocity at an instant at the maximum height,
