A cat rolls up a hill. It’s initial Velocity is 10 m/s.n It’s final velocity is 0 m/s. The time was five seconds. Calculate Acceleration
Answer:
[tex]\boxed {\boxed {\sf a= -2 \ m/s^2}}[/tex]
Explanation:
Acceleration can be found by dividing the change in velocity by the time.
[tex]a=\frac{v_f-v_i}{t}[/tex]
The final velocity of the cat was 0 meters per second and the initial velocity was 10 meters per second. The time was 5 seconds.
[tex]v_f=0 \ m/s\\v_i=10 \ m/s\\t= 5 \ s[/tex]
Substitute the values into the formula.
[tex]a=\frac{0 \ m/s-10 \ m/s}{5 \ s}[/tex]
Solve the numerator.
0 m/s-10 m/s= -10 m/s[tex]a=\frac{-10 \ m/s}{5 \ s}[/tex]
Divide.
[tex]a= -2 \ m/s^2[/tex]
The acceleration of the cat was -2 m/s². The negative acceleration indicates slowing down or stopping.
Why is gravity so weird?
Answer:
why gravity is so weird?
this is my opinion
Explanation:
One possibility — speculative at this point — is that in addition to the three dimensions of space that we notice every day, there are hidden extra dimensions, perhaps “curled up” in a way that makes them impossible to detect. If these extra dimensions exist — and if gravity is able to “leak” into them — it could explain why gravity seems so weak to us.

A bat, flying toward the east at 2.0 m/s, emits a shriek that is reflected back to it from a wall that is 20.0 m in front of the bat at the instant the shriek is emitted. Sound travels at 340 m/s in the air. How many milliseconds after emitting the shriek does the bat hear the reflected echo from the wall? *
Answer:
t = S / V where S is distance sound travels and V the speed of sound
S = 20 + 20 - v t where v is speed of bat and t time to hear echo
S = 40 - v t
t = (40 - S) / v = (40 - V t) / v substituting S from 1st equation
v t + V t = 40
t = 40 / (v + V) = 40 / (340 + 2) = .117 sec = 117 ms

Who travels the greater distance?
Whose speed is the slower?
How far would Laura travel if she drove for 3 hours at the same speed
as Clare?
Answer: A) Clare B) Clare c) 108 miles
Explanation:
Step 1
For Laura
Time taken by Laura = 3hours
Speed = 44mphn
Distance covered = speed x time
= 44 X 3= 132 miles
For Clare
Distance covered =144 miles
time = 4 Hours
Speed = Distance / Time
144/ 4 =36 mph
Step 2
a) Who travels the greater distance= Clare travels at a greater distance of 144 miles.
b)Whose speed is the slower= Clare speed is slower with 36mph
c)How far would Laura travel if she drove for 3 hours at the same speed
as Clare?
if Laura's speed = Clare speed = 36mph
time = 3hours
Distance= Speed x time
= 36 mph x 3 hours
108miles
4. Una pila recargable de 1.2 V tiene una etiqueta que dice 1 800 mAh a) ¿Cuál es la máxima cantidad de carga que puede acumular? B) ¿Y la máxima cantidad de energía? C) ¿Serán exactas todas las cifras significativas que aparecen en el dato de la etiqueta? Respuesta: a) 6480c b)7.8 x 10^3 j o 7.8 kJ c)no NECESITO EL PROCEDIMIENTO
Answer:
a) La carga eléctrica máxima que puede acumular la pila recargable es 6480 coulombs.
b) La máxima cantidad de energía acumulada por la pila recargable es 7776 kilojoules.
c) No son exactas todas las cifras significativas que aparecen en el dato de la etiqueta.
Explanation:
a) La capacidad de la batería es la corriente constante suministrada por la batería durante su tiempo de servicio. En este caso, puesto que la batería tiene una capacidad de [tex]1800\,mAh[/tex], significa que la batería entrega una corriente de 1.8 amperios durante una hora. La máxima cantidad de carga es estimada por la siguiente expresión:
[tex]q = C\cdot \Delta t[/tex] (1)
Donde:
[tex]C[/tex] - Capacidad de la pila recargable, medida en amperios-hora.
[tex]\Delta t[/tex] - Tiempo de servicio, medido en horas.
[tex]q[/tex] - Carga eléctrica, medida en coulombs.
Si tenemos que [tex]C = 1.8\,A[/tex] y [tex]\Delta t = 3600\,s[/tex], entonces la máxima cantidad de energía que puede acumular es:
[tex]q = (1.8\,A)\cdot (3600\,s)[/tex]
[tex]q = 6480\,C[/tex]
La carga eléctrica máxima que puede acumular la pila recargable es 6480 coulombs.
b) La máxima cantidad de energía suministrada por la batería ([tex]E_{max}[/tex]), medida en joules, es definida por la siguiente expresión:
[tex]E_{max} = q\cdot V[/tex] (1)
[tex]E_{max} = (6480\,C)\cdot (1.2\,V)[/tex]
[tex]E_{max} = 7776\,J[/tex]
La máxima cantidad de energía acumulada por la pila recargable es 7776 kilojoules.
c) Sabemos que las unidades estándar del voltaje y la capacidad son el volt y el amperio-hora, respectivamente. Entonces, si asumimos que las cifras significativas quedan representadas por el número de decimales y que se considera razonable que haya una cifra significativa, entonces tenemos que cada variable es en formato de ingeniería:
[tex]C = 1.8 Ah[/tex] y [tex]V = 1.2\,V[/tex].
Al mutiplicarse cualquiera de estas cantidades por un número con una cifra significativa deja con un producto con dos cifras significativas. Por tanto, se pierde precisión al realizarse operaciones de multiplicación.
No son exactas todas las cifras significativas que aparecen en el dato de la etiqueta.

A ships initial position is 25 km east of the origin. What is the ship’s final position if it sails at a constant velocity of 42 km/h east in exactly 1.5 h? (Note: answer in km)
Answer:
88km E
Explanation:
25 km is added already
then if we take the formula of speed(V)
V=d/t
and rearrange it to subject d (distance)
d= V x t
we get
d= 42km/h x 1.5hrs
we get
63 km
now if we add the already travelled 25 km to this additional distance
63km + 25km = 88km
Thus the final distance traversed by the ship from its origin is
88km E

Explanation:
A wagon is pulled to the right using a force of 20 N and to the left using a force of
30 N. What is the net force on the wagon?
Answer:
Net force = 10N
Explanation:
Net force refers to the sum total of all the forces acting on an object. Net force is denoted by Fnet. According to Newton's third law of motion, for every action force, there is an equal and opposite reaction force. This means that an object with net force is an unbalanced force.
In this case, a wagon is pulled to the right using a force of 20 N and to the left (opposite direction) using a force of 30 N. This means that the net force will be the difference of the two forces acting on the object i.e
Fnet = Fa - Fb
Fnet = 30N - 20N
Fnet = 10N

Write a scientific explanation that describes the interaction between the two skaters caused by the forces that they apply to each other.
Explanation:
... in every interaction, there is a pair of forces acting on the two interacting objects. The size of the force on the first object equals the size of the force on the second object. The direction of the force on the first object is opposite to the direction of the force on the second object. Forces always come in pairs - equal and opposite action-reaction force pairs.
