Answer:
Work done, W = -318.19 Joules
Explanation:
It is given that,
Force acting on the object, F = 50 N
Distance covered by the force, d = 9 m
Angle between the force and the distance traveled, 
The work done by an object is equal to the product of force and distance traveled. It is equal to the dot product of force and the distance. Mathematically, it is given by :


W = -318.19 Joules
So, the work done by the force is 318.19 Joules. The work is done in opposite to the direction of motion. Hence, this is the required solution.

Answer:
Particle radiation
Explanation:
nuclear process is in atom nucleas maybe emit the electron ,neutrino or anti-neutrino
Answer:
Q1. Young rocks are found on top, and old layer are found on the bottom.
Q2. Layers of sedimentary rock. Fossil layers are fossils that formed in sedimentary rock. When, over a long time, layers and layers of sediments get deposited on top of each other, the weight of the top layers presses down on the bottom layers, forming them into rock called sedimentary rock
Explanation:
Sedimentary rocks are deposited one on top of another. Therefore, the youngest layers are found at the top, and the oldest layers are found at the bottom of the sequence.
Answer: 329.28 m/s
Explanation:
Given that:
Distance of sound = 823.2 m
Time taken for sound = 2.5 seconds
The speed of traveling sound = ?
Speed is obtained by dividing the distance travelled by the time taken for the travel.
Speed = Distance / time
Speed = 823.2m/2.5 seconds
Speed = 329.28 m/s
Thus, the sound traveling as fast as 329.28 m/s
