A concave mirror has a radius of curvature of 10 cm. Find the location an height of the image if the distance of the object is 8cm and the height of the object is 1.5 cm, using a scaled ray diagram

Answers

R=10
F=R/2
F=10/2=5
F=-5(CONCAVE MIRROR)
U=-8(CONCAVE MIRROR)
HEIGHT OF OBJECT=1.5
V=?
HEIGHT OF IMAGE=?
I/F=1/U+1/V
-I/5=-1/8-1/V
-1/V=-1/5+1/8
-1/V=-8+5/40
-1/V=-3/40
1/V=3/40
V=40/3

HEIGHT OF IMAGE/HEIGHT OF OBJECT =-V/U
HEIGHT OF IMAGE=40/3*1/-8*15/10

QUESTION 2 OF 10What is one way that nuclear fusion differs from nuclear fission?
A. Nuclear fusion is used to power aircraft carriers.
B. Nuclear fusion is used in power plants to produce electricity.
C. Nuclear fusion requires very high pressures and temperatures.
D. Nuclear fusion occurs spontaneously on Earth.

Answers

C. Nuclear fusion requires very high pressures and temperatures.

Nuclear fusion involves the process of combining two light atomic nuclei to form a heavier nucleus, and it requires extremely high temperatures and pressures, as found in the core of stars. In contrast, nuclear fission is the process of splitting a heavy atomic nucleus into two or more lighter nuclei and typically occurs in nuclear power plants to produce electricity.

Mary walked north from her home to Sheila's home, which is 4.0 kilometers away. Then she turned right and walked another 3.0 kilometers to the supermarket, which is 5.0 kilometers from her own home. She walked the total distance in 1.5 hours. What were her average speed and average velocity?

Answers

The answer is speed: 4.7 km/h, velocity: 3.3 km/h.

Distances and time are given:
d1 =  4 km
d2 = 3 km
d3 = 5 km
t = 1.5 h

The speed can be expressed as a distance (d) divided by time (t). The average speed (s) is total distance travelled divided by time:
s = (d1 + d2)/t = (4+3)/1.5 = 7/1.5 = 4.7 km/h

The average velocity (v) is total displacement (d₁) from the starting point divided by time. Since Mary's starting point was home, and she walked to the supermarket, which is 5.0 kilometers from her own home, her displacement is 5 km:
v = d₁/t = 5/1.5 = 3.3 km/h

HELP ME PLEASEIn which prenatal stage is a fetus' genitalia clearly male or female?
A. zygote stage B. germinal stage C. embryonic stage D. fetal stage

Answers

In the fetal stage, the genitalia of a fetus is developed. Thus option D, the fetal stage is correct.

What is the prenatal stage?

The time period from the formation of the zygote to the parturition is called the prenatal stage and it is also known as the antenatal stage. In this stage, division and differentiation of the zygote take place to form an embryo, and then the development of the embryo to form a fetus.

The prenatal stage consists of 3 stages:

1) Germinal stage

2) Embryonic stage

3) Fetal stage

The time period of the first two weeks after conception is known as the germinal stage, from the third to eighth week is the embryonic stage, this stage begins after implantation, and from the ninth week to the parturition is the fetal stage. The genitalia of a fetus can be clearly differentiated by the twelfth week.

Therefore, option D, the fetal stage is correct.
