Answer:
Explanation:
simple, just use F = ma
assume that the acceleration is any positive value <em>a</em>
The force F must accelerate both sleds
F = (2m + m)<em>a</em>
The force T must accelerate the rear sled
T = m<em>a</em>
T/F = m<em>a</em>/3m<em>a</em> = 1/3
Answer:
To write 50000 in scientific notation, we will have to move the decimal point four points to left, which literally means dividing by 104 . Hence in scientific notation 50000=5×104 (note that as we have moved decimal four points to left and thus divided by 104 , we are multiplying by 104 to compensate.
Explanation:
Speed is calculated by distance divided by time
Answer:
Volume flow rate = 
Explanation:
The volume flow rate through a channel can be gotten by multiplying its area and its velocity.
The channel under consideration is a circular channel. Hence, the cross-sectional area can be calculated by using the relation for calculating the area of a circle
Cross-sectional area = 

volume flow rate= 
Volume flow rate = 
The momentum of a neutron p = 586.25 kg m / s.
<u>Explanation:</u>
The product of mass and the velocity gives the momentum of an object and it is a vector quantity. It is denoted by the letter p. The unit of momentum is kilogram meter per second (or) kg m / s.
Given mass m = 1.675
10, velocity v = 3.500
10
Momentum, p = mv
where m represents the mass,
v represents the velocity.
momentum p = (1.675
10)
(3.500
10)
momentum p = 586.25 kg m / s.
