Answer:
a. Net force = 40 Newton.
b. Acceleration = 8m/s²
Explanation:
Given the following data;
Force on postive x-axis = 90N
Force on negative x-axis = 50N
Mass = 5kg
a. To find the net force;
Net force can be defined as the vector sum of all the forces acting on a body or an object i.e the sum of all forces acting simultaneously on a body or an object.
The net force is equal to the difference between the two forces applied because they are acting in opposite directions.
Net force = 90 - 50
Net force = 40N
b. To find the acceleration;
Acceleration = net force/mass
Acceleration = 40/5
Acceleration = 8m/s²
Answer:
9m/s^2
Explanation:
solution,
Given. Initial velocity (u)=0m/s
Final velocity (v)=45m/s
Time taken(t)=5sec
Acceleration (a)=?
we know,
a=v-u/t
=45-0/5
=45/5
=9m/s^2
Therefore acceleration (a)= 9m/s^2
"Period" and "frequency" of waves and oscillations are simple reciprocals. They're not related to the wavelength or speed.
Period = 1 / frequency
Period = 1 / 23.4 Hz
<em>Period = 0.043 second</em>
Answer:
I agreed because, gravity keeps the moon in orbit and causes a pop fly to smack into your baseball mitt.
Explanation:
yes.
Answer: I= 0.583A
R=205.83ohms
Explanation: Power= I*V
Where I= current and V = potential difference
I=P/V
I= 70/120
I=0.583A
To find resistance
Using ohms law
V= IR
R=V/I
R= 120/0.583
R= 205.83ohms
