1)
first you find the maxium force that the car can produce.
f=ma
Fmax=(1100kg)(6m/s^2)
then use f = ma again to find the accel with the passengers
Fmax=(1100kg +1650kg)(a)
=> a = (1100kg)(6m/s^2)/( 1100kg +1650kg)
= 2.4 m/s^2
Answer:
1428.6m/s²
Explanation:
Given parameters:
Force applied on the body = 40N
Mass of the body = 28g
1000g = 1kg
28g will therefore be 0.028kg
Unknown:
Acceleration = ?
Solution:
To solve this problem, we use the expression derived from Newton's second law of motion.
Force = mass x acceleration
Insert the parameters and solve;
40 = 0.028 x acceleration
Acceleration = 
= 1428.6m/s²
Answer:
0.0222T
Explanation:
Frequency (f) =90 rev/s
Voltage = 1.15 v
Radius of coil = 1.00cm
= 0.01m
No of turns of wire (N) = 291
ω = 2πf
ω = 2π(90)
ω = 180π
A(t)= πr².sin ωt
= π(0.01)². Sin180πt
= 0.0001π.sin180πt
Differentiate A(t) with respect to t
dA/dt = 0.0001π . 180π . cos 180πt
EMF = - NB(dA/dt)
B = EMF/N(dA/dt)
B = 1.15/ -291(0.0001π . 180π . cos 180πt)
At the moment of induced voltage, cos180π = 1
B = 1.15/ -291(0.0001π . 180π . 1)
B = 1.15/ -51.7
B = 0.0222 T
The strength of the magnetic field = 0.0222T
The function y must be equal to 0 on any interval on which it is defined. The function y must be increasing (or equal to 0) on any interval on which it is defined.
Analysis of solution by seeing differential equation:
Given differential equation is: y' = (1/2)y2
How do deduce the results just by seeing them?
The equation tells us that:
rate = positive of ( y^2 )
rate = positive of (positive or zero) = positive or zero
Thus, the rate is positive or zero no matter what value we put in the place of y from its valid domain, since.
When the rate is positive or zero, that means the function will never grow upwards. Thus, either increasing or staying at the same level.

Answer:
I think it turns into heat (thermal) energy if I'm right
