Answer:
its not moving at a constant velocity because it is slowing down
Explanation:
The direction of the curl of magnetic field is determined by right hand thumb rule. Suppose you are holding a current carrying wire in your right hand such that the direction in which your thumb points is the direction of the current in the that wire then the fingers curled will determine the direction of the magnetic field. In B, the direction of current in the wire is towards ourself. Now, use right hand rule such that the thumb points towards yourself. The curled fingers rotate clockwise. Therefore, the magnetic field is in anti-clock direction
Answer:
Atoms cannot be divided using chemicals. They do consist of parts, which include protons, neutrons,...
Each electron has a negative electrical charge.
Each proton has a positive electrical charge.
Each neutron is electrically neutral. In other words, neutrons do not have a charge
Explanation:
Answer:
The distance s of how far the ball will go at the highest setting = 2.25m
Explanation:
Let consider x to be the representative of the compression and the distance to be s
Recall that:
By cross multiplying
Thus, for the first setting
x = 1 , s = 0.25
for the second setting
x = 2, s = 1
1 = 0.25A + B --- (1)
4 = A + B ----- (2)
From (1); let B = 1 - 0.25A and substitute it into (2)
4 = A + 1 - 0.25 A
4 - 1 = A - 0.25 A
3 = 0.75 A
A = 3/0.75
A = 4
From (2)
4 = A + B
4 = 4 + B
B = 4 - 4
B = 0
Therefore, for the highest setting, where x = 3
Then :
will be:
3² = 4s + 0
9 = 4s
s = 9/4
s = 2.25 m
∴
The distance s of how far the ball will go at the highest setting = 2.25m
The momentum of daemon and his cart as he rolls immediately after they are no longer in contact 81.69kgm/s.
<h3>What is momentum ?</h3>
In Newtonian physics, an object's linear momentum, translational momentum, or simply momentum is defined as the product of its mass and velocity. It has both a magnitude and a direction, making it a vector quantity. If an object has mass m and velocity v, then its momentum p is given by
p = mv
Therefore, the Newton-second may be used as the unit for momentum (Ns). In the CGS system, the unit of momentum is the gram-centimeters per second (gcm/s), where the mass is measured in grams and the velocity in centimeters per second.
Total momentum of the system = momentum of christine's cart + momentum of daemon's carttotal momentum of the system
= 37.8 kgm/s + 43.89kgm/s
= 81.69kgm/s.
