Answer
given,
mass of satellite = 2400 Kg
speed of the satellite = 6.67 x 10³ m/s
acceleration of satellite = ?
gravitational force of the satellite will be equal to the centripetal force
Assuming the radius of circular orbit = 8.92 x 10⁶ m
now,
F = 11970.11 N
acceleration,
a = 4.98 m/s²
I say it is false that is the correct answer
Voltage (V)= Current (I) * Resistance (R)
V=IR=10*12=120volt
*This is a common answer of mine*
Hope this helps!
Answer:
1.47 J/kg
120 m
Explanation:
The maximum height it can jump in a single leap 15 cm, = 0.15 m
to get the kinetic energy per kg of mass, we need to find the takeoff speed. The take off speed can be calculated by using the formula
v =
where h = 0.15
v =
v =
v = 1.715 m/s
energy per kg of mass =
1/2 * (1.715) = 1.47 J/Kg
TJe height a human can jump when compared to the flea is
2 m/2.5 mm * 15 cm =
2/0.0025 *0.15 =
800 * 0.15 = 120 m
Answer: 495.05 m
Explanation:
Given:
Initial velocity of the bullet, u = 1000 m/s, mass of the bullet, m = 10 g, mass of the wooden block, M = 1000 g,
From the swinging of the wooden block just after the collision with the bullet to its maximum height, using conservation law of mechanical energy we have that,
1/2(m+M) = (m+M)gh
Where h = the vertical height of the block in the direction will the block swing, and g = acceleration due to gravity = 10
=> v=
Using the conservation law of linear momentum,
mu = (m+M)v
mu = (m+M) (where v=)
=>h = *
h=
