Answer:
<h2>5.25 kg.m/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 0.15 × 35
We have the final answer as
<h3>5.25 kg.m/s</h3>
Hope this helps you
I think the answer would be Switch 1 open; switches 2, 3, and 4 closed. It is letter D. This will happen when there is a low resistance and a high circuit so from the choices above, when two bulbs are open and one bulb is close, so there is a low resistance and high voltage.
Calculate force of each car:
P1 = 900 kg x 12m/s = 10,800
P2= 600 x 24 = 14,400
Degree of travel = arctan(14,300/10800)
Degree of travel = 53.1 N of E
Mass, m = 5890g
Change in temperature, θ = Final_temperature - Initial_temperature
= 315 - 462°C
= -147°C
Specific heat capacity of aluminum, c = 0.900 J/(g*K)
=mcθ
=5890g x 0.900 J/(g*K) x -147°C
=-779,247j
Answer would be C.

Answer:
the compass direction of the resultant displacement is 
south of west
Explanation:
Generally using cosine we can obtain the resultant R as follows
=> 
=> 
We can obtain the direction of the resultant by first using sine rule to obtain angle C as follows
=> ![C= sin ^{-1} [\frac{A * (sin 70)}{R} ]](https://tex.z-dn.net/?f=C%3D%20%20sin%20%5E%7B-1%7D%20%5B%5Cfrac%7BA%20%2A%20%20%28sin%2070%29%7D%7BR%7D%20%5D)
=> ![C = sin ^{-1} [\frac{20 * (sin 70)}{19.48} ]](https://tex.z-dn.net/?f=C%20%3D%20%20sin%20%5E%7B-1%7D%20%5B%5Cfrac%7B20%20%2A%20%20%28sin%2070%29%7D%7B19.48%7D%20%5D)
=> 
Then the direction is obtained as
=> 
=>
Hence the compass direction of the resultant displacement is south of west
