B. trajectory
because it is a set projectile wether or not it was calculated
plz mark brainliest
The overall charge on a neutral atom is zero.
A neutral atoms contains equal number of electrons and protons.The charge of a proton and electron is equal in magnitude but opposite in sign. A proton has a charge of 1.6 x 10⁻¹⁹C and the charge of an electron is -1.6 x 10⁻¹⁹C. Thus in a neutral atom, the charge of all the protons gets cancelled with the charge of all the electrons.
Thus a neutral atom has a net zero charge.
Ok so momentum is the product of mass and velocity. Its SI unit is Kg m/s
The marble's velocity is 0.5 cm/s and it's mass is 1.5.
Multiply this -> 0.5 * 1.5 = 0.75 g cm/s
Usually everything in Physics is converted into SI units therefore the SI measurement of the marble is 0.00000075 Kg m/s
Answer:
Va = 5000 m / 3600 s = 1.39 m/s
(Va - Vb) 60 = 10
Vb = Va - .167 = 1.22 m/s
(Va - Vb) T = 4200 Π where T is time for A to complete 1 more lap
.17 T = 4200 Π
T = 24700 Π time for A to again catch B
N = 1.39 * 24700 Answer:
Va = 5000 m / 3600 s = 1.39 m/s
(Va - Vb) 60 = 10
Vb = Va - .167 = 1.22 m/s
(Va - Vb) T = 4200 Π where T is time for A to complete 1 more lap
.17 T = 4200 Π
T = 24700 Π time for A to again catch B
N = 1.39 * 24700 Π / (4200 Π) = 8.2 laps
A will make 8 but not 9 rounds before catching B
Answer:
the velocity of the car is 30 m/s.
Explanation:
Given;
Centripetal force on the car, F = 900 N
mass of the car, m = 10 kg
diameter of the circular path, d = 20 m
radius of the circular path, r = 10 m
The velocity of the car is calculated as follows;
Therefore, the velocity of the car is 30 m/s.
