The distance of tiger's leap from the base of rock is 5.58 m
It is a question of two dimensional motion
The time of motion in two dimensional motion is given by:
t=
where y is the height and g is the acceleration due to gravity
y is given to be 7.5m and let us assume g to be 9.8 m/s^2
t =
= 1.24s
Using time and speed,
We know that distance is the product of speed and time,
Distance= speed x time
speed is given to be 4.5 m/s
distance from the base of rock = 4.5 x 1.24
= 5.58m
Hence the distance of tiger's leap from the base of rock is 5.58 m
Disclaimer:
The acceleration due to gravity is assumed to be 9.8 m/s^2

Explanation:
Goooogle, so I hope this helps somewhat
Also, isn't this a History question? You put physics lol

Answer: C. 7.67 W </h2>
Explanation:
Firstly, we are told the three resistors are <u>connected in parallel</u>, this means we have to use the following equation to find the total resistance of the circuit:
(1)
Where: , ,
Solving (1):
(2)
(3)
(4) This is the total resistance of the circuit
On the other hand, the total power of this circuit is given by the following equation:
(5)
Where is the total voltage of the circuit.
Solving:
(6)
Finally:
(7) This is the total power of the circuit in Watts (W)
Answer:
Wilhelm Roentgen, Professor of Physics in Worzbury, Bavaria, was the first person to discover the possibility of using electromagnetic radiation of create what we now know as the x-ray
Answer:
Work=1800 J
Speed=3m/s
Explanation:
Work is product of force and distance moved, expressed as
W=Fd
Where F is force and d is distance in meters
Substituting 300 N for force and 6 m for d then
W=300*6=1800 J
Kinetic energy is given by
KE=½mv²
Where m is the mass and v is velocity
Here, KE=W hence
W=½mv²
Making v the subject then
Substituting 1800J for W and 400 kg for m then
Therefore, velocity is 3 m/s
