Answer:
option A
Explanation:
given,
For exerted by the worker = 245 N
angle made with horizontal = 55°
we need to calculate Force which is not used to move the crate = ?
Movement of crate is due to the horizontal component of the force.
Crate will not move due to vertical force acting on the it.



hence, worker's force not used to move the crate is equal to 200.69
The correct answer is option A
An electromagnetic , transverse, wave is a wave that goes up and down, such as light that does not need a medium to travel
While compressional, longitudinal wave such as sound require a medium to travel and can be compressed
hope this helps

P = Power
W = Work
Delta T = Change of Time
So:
P = 35 Joules
Delta T = 70 secs
W = ?

* Joule/Sec = Watt
Answer: The power used to do this task was 0.5 Watts.
1) Answer:
98 N
Explanation:
The weight of an object is given by:

where m is the mass of the object and g is the gravitational acceleration. In this case, m=10 kg, therefore the weight of the lemur is

2) Answer:
87 N
Explanation:
The value of g at the International Space Station is
. Therefore, the weight of the lemur on the Space Station will be
